If there is a homosexuality gene, then it must be a defective mutation since it would not lead to the survival of a species.
Whether you take a biblical or a Darwinian perspective, its very difficult to call homosexuality “normal”. Also the psychological imprinting that occurs when a child is sexually molested and cultural factors (such as positive portrayal of homosexuality in the media ) far outweighs any purported genetic factor. The next goal on the homosexual agenda will be to abolish age of consent laws.
My ex-BIL, divorced my SIL, after 6-8 years of marriage and a beautiful daughter, to go into the homosexual lifestyle.
This experience, of seeing him convert, and many unrelated experiences with many others convinced me that is truly a chosen lifestyle. Nothing more, nothing less, almost always traceable to their environment (which may have included sexual abuse or overly protective mothers).
Generally, geneticists settle for some genetic influence of
rather undefined degree, most agreeing that many genes (from
at least five or six to many hundreds) contribute to any particular human behaviour.
• A genetically dominated SSA caused by such a cluster of genes could not suddenly appear and disappear in families the way it does. It would stay around for many generations. So SSA is not produced by many genes.
• The occurrence of SSA in the population is too frequent to be caused by a chance mutation in a single gene. So a single gene is not responsible for SSA. Nor would many genes all mutate at once.
• SSA falls more naturally into the category of a psychological trait.
