There are so many things laughable about this thread.
First, that Christians think they invented and have a monopoly on marriage. Sorry, but you don't. You neither own the institution nor the word. People were getting married long before being afflicted with your own form of mass delusion, and they will probably be getting married long after it dies out.
Second, you're right, this is a religious issue. The government should not have a say in marriage. But they do, and as long as they do, they have absolutely no right to use it to grant benefits to certain people and deny them to others. This is mainly a problem with taxation. Take away all tax and social benefits from "marriage" and you can keep it. Trust me, I don't want to be a part of your religion any more than you want me in it.
Third, since you're saying it's up to the religions to define and perform marriage, then you need to stop following that up with the complete bullshit statement that this means gays should not be allowed to marry. There is no one "Christian" church, and no one Christian position on this topic. So if a religious group wants to marry gays, what exactly gives you the right to stop them?
And to the anti-gay King Theocrat, no, we do not choose to be gay. Who in their right minds would choose to be gay and know that for the rest of their lives they have to put up with the kind of bigotry and stupidity that you and you ilk spout on a daily basis? Out of curiosity, when was the first time that you decided you were going to be attracted to women? Did both sexes turn you on before that point?
Trust me, I don't care about your religion. I don't care about your practices or your beliefs. I don't want anything to do with it. But that also means that you need to keep your religious beliefs out of my life. When religious people decide they have the monopoly on morality and feel they should enforce their own draconian views on the world we end up with things like the crusades, the inquisition, the holocaust, people flying planes into buildings, and mass suicide. That's not a road I care to walk.
