If homosexuality is really a genetic thing, then wouldn't they eventually become extinct? They wouldn't be able to reproduce and the gene would fade away.

I don't think it's genetic, but your argument is flawed. Most homosexuals have normal sex at some time in their lives. Some are even married (I mean real marriage).

Which has always been my point. If you can get aroused to have sex with the opposite sex, then you ARE NOT GAY. It is a choice.

Well said,
Personally I think the reasons for people being Gay are miriad--some may be born with it, some learn it, some due to trauma, etc. Psychiatrists have been unable to explain why we do most of what we do to any real exacting degree, so why should homosexuality be any different.
