So you don't believe homosexuality is a choice? How can you say that? Is murder a choice? Is child abuse a choice? Is beating your dog a choice? Is sexual perversion a choice? I believe homosexuality is absolutely a choice, given the homosexuals I know and have known - everyone chooses who to have sex with, unless you are forced. I will never defend homosexual special laws by the thought police. I don't condone violence against anyone but I also don't believe homosexuals should have special laws protecting their behavior. That is ludicrous.
Second, there is little bearing to the argument "everyone chooses who to have sex with." By that stance, one's sexuality can be confirmed only by whether they have had sex with someone, which really isn't the case. If it was, then we would all be asexual until we each had sex. In reality, sexuality is not something gained through action, it's the tendancy to be attracted to a gender (I'm, of course, generalizing this).
If you honestly believe that being gay or straight (or somewhere in between) is a choice, then how can *anyone* be labeled gay or straight unless they're called that in the act of doing it? If it's the action (their choice of actions), not some intrinsic value, then they're only gay while actually engaging in gay sex. This, I'd hope you agree, doesn't make much sense.
