The contention that homosexual orientation (as distinct from homosexual behavior) is a recent and local phenomenon is not supported by the evidence. … - J. Michael Bailey

To me, cases like that really scream out, ‘Hey, it’s not out there. It’s in here.’ There’s no indication that this mother is prone to raise very feminine boys because his twin is not that way.

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.

“Social constructionism” (or “social constructivism”) is a term that might be familiar to anyone who has taken a humanities course at an American or European university since 1990, but it might otherwise sound odd. It is difficult to explain social constructionism in a way that satisfies social constructionists. They think this is because they are profound and people like me simplistic. I think it is because they aren't very clear, and to the extent they are clear, they are incorrect.
