Can we protect traditional marriage from its defenders?

Fear not, traditional marriage! The Republican Party is coming to rescue you from the chance that loving gay couple soon may enjoy equal legal protection.

Yes, U.S. senators Larry Craig (R-Idaho) and David Vitter (R-La.) are co-sponsoring the Marriage Protection Amendment, which would make marriage constitutional only for heterosexual couples. Larry Craig was charged with lewd conduct on June 11, 2007, after allegedly soliciting a police officer for gay sex. Vitter was identified that July as a patron of a brothel owned by the late Deborah Jeane Palfrey.

 Irony really is dead.

How on earth can you propose a constitutional amendment to "defend the institution of marriage" when your own peccadilloes have robbed you of any claim to the moral high ground? To put it another way, it's (not) great that they want to defend marriage from including couples; but who's going to defend it from them?

My mind would boggle if I still had one left.
