wtf is wrong with these people?

From a Salon article today:

"It should be an inalienable right, guaranteed by our Constitution, to live in a marriage-based society," said Robert Knight, director of the Concerned Women for America's Culture and Family Institute. "When you create counterfeit marriages and put them into the law, you're undermining society's most important safeguard against tyranny."

I can't even begin to fathom where one comes up with this sort of rhetoric, and I can't imagine that working as a convincing argument against gay marriage. I know it works, and I know people believe that, and it just makes me so sad.
