You're right, this is a problem.
If something is heritable but also uncommon, it should be possible for selection pressure to act on it. So why doesn't it? That clarifies the issue for me. What I wrote before (in this comment thread) now seems mistaken. Thank you for helping me to understand better.
It seems my original question was partly due to a misunderstanding. The crucial fact about homosexuality isn't just the lowered fitness or relatively high incidence, but the (partial) heritability. Then the only relevant remaining question is: can we quantitatively estimate the reduced fitness due to homosexuality and so calculate the unlikelihood of its 3% rate being due to chance, drift, etc?
Congratulation for good updating.
