Perhaps the weakness of evolutionary thought is that it can explain just about anything. In particular organisms are not perfect, and therefor will have features that do not really help them. But mostly they are well adapted.
The reason that homosexuality is an obstacle to survival is not homophobia or STDs, but rather that they simply may not have children. It is the survival of the genes that counts in the long run. But until recently homosexuals tended to suppress their feelings and so married and had children anyway, hence there being little pressure to suppress it.
