I know of no convincing evidence that the disorder is inborn.
Perhaps no convincing scientific data. I have known gay males whose parents say that by age 3, they were noticeably feminine, as opposed to an older, masculine brother. They preferred dolls to boy’s toys, even when the parents tried to “macho-ize” them. By 12, they had crushes on other males.
This is indicative of an inborn disorder. Other data would point to a larger % becoming homosexual by way of poorly guided psycho-social development. It is THIS group which is being harmed by the gay agenda. The first group deserve compassion.
How do you think it got started?
