Gay marriage

I'm not determined enough to read all of this. But, (edit)while(endedit) I will say that denying a homosexual couple rights is against what's right, I think we evolved/were created as male and female for a reason.

My reasoning?

Penis into vagina.
Shit out of ass.

Given that shit is waste, broken down bile and avoided by most reasonable people, I don't understand how people can consider that to be right. It seems to go against our species.

That's really all I'm going to say, so call me ignorant or whatever, I just don't plan on responding.
