1. Yes there are homosexual tendicies in all species, but there's also a survival trait and when it comes down to it you pick survival, I would say at least.
2. Yeah, I don't like that a kid can marry someone with consent, either, because of obvious reasons. And yes, I know that marriage isn't just Christian, but the point I was trying to make is that if the government were to push a certian type of marriage it should be heterosexual because again, survivial.

An internet article can't show you the three-generational-old fort in the woods that your great-grandfather, grandfather, and father built up, an internet article can't pass down a doll or worn stuffed-anaimals that your great-grandmother stitched together. It's just that there's a guiene... feeling? No, I can't think of the words. :P I dunno, it's just something special that a mother can teach and a father can teach. Sorry if I sound aggressive or anything, I don't mean to. xP
