Evolution and Genetic Homosexuality

[dknightx]

This is an honest question and something that I was thinking about last night. How can evolution and genetic homosexuality coincide? It would seem to me (and my very basic understanding of both items), that if we supported evolution, and homosexuality was genetic, we would see a natural "weeding out" of people born homosexual ... I mean, you can't really continue a species without procreating (or being attracted to) the opposite sex. So if we follow the idea of "survival of the fittest", wouldn't we be seeing a lot less homosexuality? (instead of more?).

Also, if homosexuality is genetic, then would other types of fetishes be genetic as well? Like, what if you only liked people of a certain race, or what if you were only turned on by animals? Where do we draw the line between what is a choice and what is genetic?

thanks in advance for your time and thought out responses.
