The proponents of same sex marriage have not offered any positive argument for redefining an institution that has served mankind well for thousands of years. When it comes to a change in the status quo, the burden of proof is upon those who seek a change in it. I agree. My point was that a marriage is not just a joining of two arbitrary people who happen to be heterosexual. The fact that there is exactly one male is key. If gays want to figure out how to have marriages with exactly one male, fine. I've never heard of them seeking that, though.
Allowing same sex marriage threatens religious liberty. After all, if the right to have any family arrangement is a fundamental human right protected by the courts, than it stands to reason that if you oppose same sex marriage on moral grounds, you belong to a suspect category. In one fell swoop, the state can declare politically incorrect thought about marriage a "hate crime" and punish any one who thinks marriage is only a union of a man and a woman. That's already happened in Canada and may well happen here in this country. Its not just about what Adam and Steve do in their bedroom - same sex marriage has public policy, political and moral consequences that affect each and every one of us.
