There are two quite different definitions of the term sexual orientations:
Some conservative Christian organizations define "sexual orientation" very
broadly as a list of parameters that define all aspects of one's sexual
desires. For example, a man might be particularly attracted to women who are
of medium height, a few years younger than he is, with red hair. This
collection of gender, height, age and hair color factors would define the
man's sexual orientation. Thus, homosexuality -- being attracted only to
members of the same gender -- would only be one component of a person's sexual
orientation. Pedophilia -- being sexually attracted to children -- would be
another part for a small minority of adults. So would bestiality -- being attracted to animals.
Accepting this definition
would complicate government legislation dealing with sexual orientation. Any civil rights legislation which extends protection to persons
on the basis of their sexual orientation would, under this definition,
also decriminalize pedophilia and bestiality. To our knowledge, this definition does not
appear in any dictionary or medical text; it seems to be used only by a
minority of fundamentalist and other evangelical Christians.
Almost all human sexuality researchers, gays and lesbians, religious
liberals, and professionals in the medical and therapeutic professions
define a person's "sexual orientation" according to the gender(s) of the
person to whom that person is sexually attracted:
Heterosexuality includes over 90% of adults -- those who are sexually
attracted only to members of the opposite gender.
Homosexuality includes a small minority of adults -- perhaps
5% -- who are attracted
only to
members of the same gender.
Bisexuality includes a smaller minority of adults who are attracted to both men
and women, although not necessarily to the same degree.
Beliefs about homosexuality by theologians and scientists:
Normally, there are minimal conflicts between scientists and theologians.
They usually work in different areas of study. Theologians are rarely
interested in the tensile strength of steel. Scientists are rarely interested in
the soul, salvation, heaven or hell. But there are some shared areas where both
scientists and theologians promote their beliefs. Often, these beliefs are in
conflict. As of 2007, the main areas of conflict are the
origins of the universe, and various human sexuality topics.
Homosexuality is measurable and is thus a legitimate area of study for human sexuality researchers. They have generally
concluded that adult human sexuality comes in the three natural, normal, unchosen, and unchangeable orientations defined above.
Homosexuality is mentioned in
the Bible, the Qur'an, writings of the Baha'i
Prophet Baha'u'llah, and in other texts considered sacred in various world religions. Thus, homosexuality is also a
legitimate area for theologians to study. Speaking generally:
Religious conservatives believe that their holy texts were written by persons who were inspired by
God. They produced books which are inerrant -- free of error. They base their beliefs about
homosexual behavior on their interpretation of the Bible. They conclude that it is unnatural, abnormal, chosen and changeable
behavior.
Religious liberals generally approach the Bible as a historical
document. They note that the authors of their religious texts lived in
a pre-scientific era and had no special knowledge of sexual
orientation. Religious liberals base their beliefs about homosexual orientation
both on
their interpretation of the Bible, and on the findings of sexuality
researchers. They generally agree with scientists thathomosexuality is
a natural, normal, unchosen, and unchangeable orientation.

Speculations into the cause of a homosexual orientation:
People hold various conflicting beliefs about the "cause" of sexual orientation,
including:
Some people have no opinion. They point to many of the scientific
studies which are inconclusive. For example, one experiment showed that
male homosexuals have a different brain structure than heterosexuals.
But this raises the question whether the difference in structure causes
a homosexual orientation, or whether the opposite is true: the different
structure develops as a result of homosexual behavior.
Some people speculate that
homosexuality as a disease, like alcoholism. But this seems
doubtful, because:
"Homosexuality exists without external impetus; it
exists without the introduction of foreign chemicals and without the
infliction of external actions by others." 3
Some people speculate that homosexual
behavior is caused by a moral weakness, like lying or stealing. But
that also seems unlikely, because homosexuality "...exists in animal species in which these actions
-- these
"sins"-- cannot occur." 3
Most conservative Christians speculate that homosexual behavior is
caused by poor parenting skills in the homosexual's family of origin.
Reparative therapy is based on this belief.
Many surveys conducted by conservative Christians find that gays did not
bond closely to their fathers, and lesbians did not bond well with their
mothers. But other studies show that no such parenting problem exists.
Some conservative Christians believe that people become
homosexual because it is taught to them as children. 10
This motivates religious conservatives to oppose education classes which
discuss sexual orientation, and to campaign against gays and lesbians
having the right to adopt children. However, it is doubtful that the
childhood environment can convince a person to become gay or lesbian. If
it could, then one would expect a greater incidence of homosexuality
among individuals who were brought up by gay parents, in comparison to
those raised in heterosexual homes. No such difference is observed.
Some conservative Christians believe that people make a conscious
choice to become gay or lesbian at puberty. 10 Again,
this is doubtful, because child psychologists can accurately identify
which pre-school children will grow up to be homosexual. Also, it has
been argued that nobody in their right mind would choose to become gay
or lesbian and subject themselves to immense amounts of homophobia,
discrimination, physical abuse, and emotional-spiritual abuse.
Finally, other conservative Christians believe that some homosexuals"are possessed by one or more demons," either before or after
birth. 10 This is a theological belief among many
religious conservatives who believe in the
inerrancy of the Bible. After all, there are many passages in the
Christian Scriptures (New Testament) which describe demon possession as
a cause of epilepsy, schizophrenia, psychotic behavior, etc. Thus, it is a small
leap to include homosexuality among this list of disorders. However,
mental health professionals have rejected of the possibility of
indwelling demonic beings for the past many generations. Belief in spirit
possession is almost extinct.
The most common belief of human sexuality researchers is that
homosexual orientation is caused by a pre-existent genetic makeup which
is established at conception. This may be triggered early in life by an
unknown factor in the environment. If the factor is not present, the
gene or genes causing homosexuality will not be triggered, and the
person will grow up heterosexual.
Some studies and indicators of the cause(s) of homosexual orientation:
Studies into the causes of sexual orientation have concentrated on
male homosexuality. Six studies are described in greater detail in
another essay on this web site. More studies
are described in an additional essay. All of
the studies show that genes play a significant role in determining
homosexual orientation. None of the studies show that the environment is
solely responsible. We did not pick and choose the studies which are
reported here. We have reported all that we have found, irregardless of
outcome.
Studies on monozygotic twins: These are twins that resulted
from the splitting of a single fertilized egg -- the zygote -- into two
separate zygotes with identical genetic structure. They are commonly
called "identical twins." Studies have been made which
involve identical twins who were separated at birth and have not been in
contact since. Studies consistently show that male homosexual
orientation is mainly (perhaps entirely) determined at conception by a
person's genes. This is such an important and definitive study
that we
describe it in more detail in another essay.
Suicide implications: The National Institute of Health (a US Federal Government agency) reported that as
many as
30% of youth suicides are by gays and lesbians. That is, homosexual young
people commit suicide at a rate as high as six times the normal value. These are
committed by youth who are certain that they are stuck being gay or lesbian for the rest of their
lives. These young
people who commit suicide may have been taught by their
families, religious institutions, schools etc to hate or reject
homosexuality. If they had any hope of changing their
orientation, they probably would seek counseling instead of killing themselves. Most
probably believe that their sexual orientation was genetically caused
and is unchangeable.
Introspection: Most sexually active adults are aware that their sexual orientation is not chosen and
not changeable. Assuming that you are a heterosexual:
Consider how you would change yourself so that you were sexually attracted to a person
of the same gender. You will realize that it is quite impossible to create feelings of
sexual attraction if they do not currently exist.
Consider at what age you chose your sexual orientation? You will realize that, as far
back as you can remember, you were either asexual or heterosexual
Irrationality of choice: In the forward to the book "We Were Baptized Too: Claiming God's Grace for
Lesbians and Gays", Anglican Archbishop Desmond Tutu of South Africa writes
"Someone has said that if this sexual orientation were indeed a matter of personal
choice, the homosexual persons must be the craziest coots around to choose a way of life
that exposes them to so much hostility, discrimination, loss, and suffering."
Brain Structure: Simon LeVay, a Neuroanatomist at the Salk Institute in California published a study
in 1991 which examined the brains of men who had died of AIDS. He found that the INAH 3 (a
structure within the hypothalamus) differed in size between heterosexual and homosexual
men. This suggested to the researcher that "sexual orientation has a biological
substrate". 2 This study has been criticized on a number of grounds. Many of his
subjects died of AIDS; perhaps the difference in structure size was caused by the disease,
or the medications that they took, not the sexual orientation. Others have
suggested that homosexual or heterosexual activity may have determined
the size of the structure, rather than vice-versa.
Hearing: A group of researchers at the University of Texas found
structural differences in the inner ears between
lesbians and heterosexual women. On average, women have more sensitive cochlea amplifiers
than men; they are able to detect softer sounds in a very quiet room. The researchers found
that lesbians had inner ear characteristics that were more like those of men. The
structure of the inner ear forms before birth and is affected during pregnancy by
androgens. 7 These findings indicate
that sexual orientation is at least partly decided before birth -- perhaps at conception.
Incidence: Gays and lesbians do not appear to be any less common in societies which condemn and
suppress homosexuals; they do not seem to be any more common in accepting societies.
This would argue against sexual orientation being learned from the
environment.
Parenting: Almost all children raised in families headed by two gays or two lesbians grow up
heterosexual. The sexual orientation of one's parents appear to have little or no
influence over the orientation of their children.
