Incidentally, as a Christian, it kinda depresses me to see so many other "Christians" out there who seem to have completely lost base with the message that Jesus was trying to get across. I really don't get what part of "Love your neighbour as you love yourself" is difficult to understand. Seriously, have any of you actually looked at what Jesus was like as a person? I'm sure that if he saw the way a lot of "Christians" treat gay people, he'd be incredibly ashamed.
In any case, none of that really has any relevance on gay marriage anyway, because religion has no place in the law. Marriage has not been an exclusively religious ceremony for an extremely long time, unless you want to also make it illegal to be married outside a church, and for atheists to get married.
