"People who find the idea "troubling" are generally religious people who see it as a threat to religious freedom. Nothing could be further from reality, however, because same-sex marriage laws have ZERO effect on any church. "
Actually, it's only marginally a threat to religious freedom, since there's not a homosexual in the universe who can make me drop my faith in Christ. What it IS a threat to, however, is sound reason and moral clarity, two ingredients that mankind needs in order to be able to find the truth. For, if you can be led to accept that two men having serial sexual relations is the same thing as a marriage, you'll accept just about anything.
