Some conservatives have accepted the argument -- most eloquently advanced by Andrew Sullivan -- that backing gay marriage actually advances a conservative position. Marriage, he argues, is a civilizing institution, and good conservatives should welcome the fact that a new group of people would like to live within its constraints of fidelity.

This argument is ridiculous: do you need a piece of paper to be faithful to someone? Gays can certainly practice fidelity without getting 'married'.
