[QUOTE=Warfish;2919347]Sorry, I still find it a bit offensive to equate the two.
One is a choice, one isn't. They are not equal.[/QUOTE]
If you offered the alternative of saying that being gay is biologically determined, but acting on it is a choice, that would carry some weight in the argument. Do you really think that people choose what they're attracted to, whether gay or straight? Our sexual preferences our usually quite nuanced and it would be a real bit of work to make someone who is, for example, really turned on by dark haired thin women be compelled to only sleep with fat women who were blond. And then there are all the other cues -- the way somebody carries themselves, the timbre of their voice, the shape of their eye, or the tone of their skin, etc.
You seem to be suggesting that same-sex attraction is somehow merely a decision, which would imply you think all sex is just a matter of learned behavior. I personally don't think that's true at all. I think there's room for some marginal adjustment, but each of has limits in what works for us.
