By the way, if you are an evolutionist, how do think homosexuality, if it is a normal condition, evolved as an adaptation that is beneficial to the propagation or survival of an individual's genetic traits?
The most convincing argument I have heard is social congruency. Homosexuality in a group of organisms increases the amount of care an empathy expressed in a group. A group that is more cohesive and cares for each other is more likely to survive. Therefore a group with homosexuality is more likely to survive than one without it. It's a pretty reasonable idea, as long as you are ok with group selection.
Note: this is only a hypothesis with no supporting evidence, though I'd imagine the evidence would be quite easy to collect. Look at two groups of organisms with different amounts of homosexualiy, and determine how their fitness differs.
