I think the issue does not lie in the fact of letting gays get married, but rather that marriage is often thought to be a religious sacrament. It is not just a piece of paper, but a blessing from God.
Don't get me wrong, I know that you can go to any courthouse in the U.S. and get married....a non-religious ceremony....but it is still a religious act.
So, to sum it up, I think the argument is that because to some God does not recognize homosexuality....and therefore gays are bad people. I am Catholic, and straight, but even I don't agree wholeheartedly with the principles of the Catholic church. I think LOVE is what really matters.
