I personally never understood some of the religious arguments against gays. The one that confuses me the most is that they're "An abomination of God". Well here's how my brain works, God is supposed to be infallible, and we are created in his image. If gays are an abomination, that means that either a) Homo sexuality is one of many characteristics of god as we are created in his image or b) God is indeed fallible and "made a mistake".
It's 3 am, haven't slept in 24 hours, and I can't think of anything more. I bet someone has a better explanation than me.
On another note, although I live in Canada, I'd like to go up against one of these people and give them a verbal beat down. In person I tend to be really good at "put on the spot" debate.
