From Brown's post on the National Organization for Marriage website:

Let me lay down a public challenge to Dan Savage right here and now: You want to savage the Bible? Christian morality? Traditional marriage? Pope Benedict? I'm here, you name the time and the place and let's see what a big man you are in a debate with someone who can talk back. It's easy to make high-school girls cry by picking on them. Let's pick on someone our own size!

Confidential to Dan: I know you're, like, six busy people locked in perpetual battle with each other, but please make this happen.

Thank you, Towleroad.

UPDATE!: "I'm traveling today and offline," says Savage. "But as soon as I get to Seattle....I'll have an answer for Brian." Stay tuned!
