So what do the Duers think of this development?
Surprisingly most of the posts I've read over at DU (and there are several threads) would not be out of place here.
It is quite entertaining over in DUmmieland right now. They have a large contingent of 1st Amendment supporters outraged by Islamic fanatics. They seem to make up most of the replies. They are followed by posters who paint all religious fundamentalists with the same broad brush. These posters are quickly rebuked with replies along the lines of, "Say what you will about fundamentalist Christians, at least they don't behead people when we make fun of them!" And finally there are the Muslim apologists who find a way to blame all of this anger on Bush's invasion of Iraq.
Like FR, DU has some pretty diverse viewpoints. Not everybody toes the far-Left moveon.org platform. I'll bet there are several people who regularly post on both forums.
