I'm gay, it's not a choice. Trust me. I can love another man just as much as you'd love a woman.
Even if it was, though, why would we govern people's loveual preference and tell them that they can't marry? I don't understand why people think it's such a big deal. It's not going to affect you in any way. Unless you're gay, that is. Gay couples still live together without gay marriage legal, it's not like it'd start turning people gay.
Some people are so ignorant.
