What You'll be reading in short?
• Whether people choose to be gay or whether the preference is biologically determined, science supports the moral decision.
• Other than genetic there could be a variety of reasons why brains could be different in homosexual & heterosexual males which research failed to consider.
• Scientists who study brain biochemistry know that the way a person thinks affects the way his brain functions.
• There is no proof linking hypothalamus size with homosexuality, either as a cause or effect.
• Even if there were some genetic commonalities among homosexuals, associated characteristics do not prove a causal link.
• Many researchers cite environmental factors as major contributors to homosexual feelings.
• Although it may be easier, psychologically, for a homosexual to believe that homosexuality is inborn but the accumulated scientific evidence suggests otherwise.
Ask this question, and you will probably receive one of two
responses:
Yes. People choose to be gay. They are making an immoral choice, or No. Sexual preference is biologically determined.
These two answers have something in common: With both of them, the science conveniently supports the moral decision.
Gay activists and the liberal media have actively encouraged the idea that homosexuality is inherited and unchangeable, and researchers have diligently sought scientific evidence to back up that claim.
The controversy began with the work of Simon LeVay, M.D. In 1991, LeVay tested the brains of 41 cadavers and noted differences between homosexual versus heterosexual males. The hypothalamus, an area believed to regulate sexual activity, was smaller in homosexual males than in heterosexuals. Dr. LeVay believed the differences proved a biological basis for homosexuality, but he failed to consider a variety of reasons, other than genetic, that the brains were different. First, all 19 of the homosexual cadavers had died of AIDS, a disease known to affect the neurological system. It could be that the disease had shrunk the hypothalamus. Second, scientists who study brain biochemistry know that the way a person thinks affects the way his brain functions; specifically, it affects the neuro-chemicals released in the brain and the way certain pathways grow and change. Could the structural brain differences have started with the difference in thoughts between homosexuals and heterosexuals, rather than with genetics? Third, there is no proof linking hypothalamus size with homosexuality, either as a cause or effect.
In 1993, Dr. Dean Hamer, a pro-gay activist, made the astounding claim in his research that there may be a gene for homosexuality. His team of researchers began a series of gene linkage studies, in which families with several homosexuals underwent genetic analysis to determine if any chromosomal variants could be found in the family and if the variant correlated with those individuals who displayed homosexuality. Although Hamer’s study sample was very small, he found a significant linkage between gays and a marker on the maternal X chromosome, Xq28. Additional studies with larger sample sizes produced conflicting results in the linkage to Xq28. It is important to note that Hamer’s experiments have never been validated; in fact, other groups of researchers have discredited Hamer’s work as non-replicable or even fraudulent.
Even if there were some genetic commonalities among homosexuals, associated characteristics do not prove a causal link.
There are many researchers who cite environmental factors as major contributors to homosexual feelings. They strongly believe that negative early childhood experiences in an unloving or non-supportive home environment are a critical part of this process.
Common elements seem to include:
• An emotionally withdrawn or physically absent father and an overbearing, fawning, or over-protective mother.
• In many cases, there are reports of physical, sexual, or emotional abuse.
• Disruption of gender identification may contribute to the development toward homosexuality. This process begins between ages two and four. During this phase, children move from their primary connection with the mother to seek out deeper attachments with the parent of the same gender.
• Peer attachments with same-sex friends also play a role in developing gender identity. Eventually, after years of interaction and bonding with same-sex peers, children enter puberty and begin to pay attention to the opposite sex. When this natural process is disrupted, it feels natural for a child to love and crave the attention of those of the same sex.
Most researchers have concluded that sexual orientation is a complex, multi-factorial issue in which biological, social, and psychological factors combine to play a role in the ultimate sexual orientation of an individual.
Although it may be easier, psychologically, for a homosexual to believe that homosexuality is inborn, the accumulated scientific evidence suggests otherwise. Homosexuals may have a genetic predisposition, but the human choice is still a factor.
