In order for a feminine boy to become transsexual, something extra must happen. What is the something extra? - J. Michael Bailey

Homosexuality might be the most striking unresolved paradox of human evolution.

The fact is that we don't know enough about hormonal effects on the human brain to have a very specific theory of how Danny's brain could have developed in a feminine direction while his body developed masculine. If Danny's body also showed signs of feminine development, this would support nature theory, but the lack of anatomical femininity does not disprove it. There has been essentially no research on boys like Danny that is directly biological. Short of dissecting the brain of a feminine boy and comparing it with normal boys' and girls' brains, it is unclear what we would even look for. However, the best conceivable direct test of nurture theory has been tried, and it failed. Amanda became Jason again.

Another environmental hypothesis that has received some enthusiasm on the political right is the idea that gay people seduce and recruit. I have never understood how this is plausible. A boy with no interest in homosexual activity wouldn't find it pleasant even if he agreed to it. How is this supposed to turn him gay?
