Born gay: NO Way!

Refuting the Distortions Promoted by the GLBTQ Activists
Distortion #1: Persons with SSA are born that way
In 1995 the Journal of Homosexuality published two double issues[1] in which a number of authors reviewed various theories suggesting a biological causation for SSA – genetic, hormonal, brain structure, sociobiological. The conclusion of the editors: “Current research into possible biological bases of sexual preference has failed to produce any conclusive evidence.”[2] The National Association for Research and Therapy of Homosexuality (NARTH) home page offers a number of articles which latest claims for the “Born that Way” theory.[3]
Supporters of the “born-that-way” theory frequently cite a 1993 study by Dean Hamer and associates who claimed to have found a “gay gene.”[4] However, other scientists have failed to duplicate their results.[5] And a genome wide study of 465 individuals by Mustanski and associates found no genetic basis for homosexuality.[6]
Some researchers have tried to cloud the issue by speaking about heritability – the way in which inherited traits may affect behavior. It is undeniable that inherited traits such as temperament, appearance, talents, and physical coordination do affect the way individuals interact with their environment, the way they are treated by others, and the way they respond to stress. There is no evidence that such inherited traits predestine a particular individual to SSA. Dr. Francis Collins, head of the Human Genome Project, explained, “there is an inescapable component of heritability to many human behavioral traits. For virtually none of them is heredity ever close to predictive.”
It has been suggested that SSA is caused by hormones. Tests on adults revealed no hormonal differences.[7] A review of the literature on hormone levels in persons with SSA found no evidence of abnormalities: “The current consensus opinion is that no causal relationship exists between adult hormonal status and sexual orientation”[8]
In 1991 Simon LeVay claimed to have found differences in brain structure of men and women with and without SSA.[9] His oft-referenced study was based on a small unrepresentative sample of men who died of AIDS. It also reveals a limited understanding of brain development. Even if differences were found that would not validate the born-that-way theory. According to Jeffrey Schwartz, author of The Mind and the Brain, “Key brain structure can change in response to your experience as an adult.”[10] Since the actions, experiences, and sexual behavior of a person with SSA may be substantially different from that of persons without homosexual experience, one would expect that differences in brain structure and response to various stimuli might be detected.
Sociobiologists have offered theories of how SSA could be genetically determined given that persons with SSA have fewer children. One theory suggests that having an uncle with SSA might increase the survival offspring of nieces and nephews. An article analyzing these theories concluded that they “were derived primarily from current stereotypes about homosexuals” and were “misconceived and without scientific merit.”[11]
Although each biological causation theory has been discredited, the media continues to announce that a biological cause for SSA has been or is just about to be discovered. For example, a study by Ivanka Savic, et al entitled “Brain responses to putative pheromones in homosexual men”[12] reported on the difference between the ways in which persons with and without SSA reacted to particular smells. The study was misreported by the Associated Press which stated that it added “weight to the idea that SSA has a physical basis and is not learned behavior.” There is nothing in the study to suggest that these differences were present at birth and not the result of experience. Dr. Savic informed the AP that their interpretation of her work was “incorrect and not stated in the paper.”[13] AP was forced to correct its report.[14]
William Byne in an article entitled “Science and belief: Psychobiological research on sexual orientation” discusses the problem of flawed research. According to the abstract, the article:
“Analyzes the assumptions and evidence that support biologically deterministic theories of sexual orientation. It is concluded that support for these theories derives as much from their appeal to prevailing cultural ideology as from their scientific merit. This appeal may explain why seriously flawed studies pass readily through the peer review process and become incorporated rapidly into the biologically deterministic canon where they remain viable even when replication attempts repeatedly fail.” [15]
Gerard van den Aardweg in an article entitled “Homosexuality and Biological Factors: Real Evidence None, Misleading Interpretations Plenty,”[16] has carefully analyzed the current claims for a biological cause and explains why each is flawed. The Whiteheads similarly have critically examined and refuted such claims and continue to evaluate each new report claiming evidence of genetic and/or biological factors associated with homosexuality.[17]
Conclusion: There is no scientific replicated evidence that SSA is genetically or hormonally predetermined or that persons with SSA were born that way.
