What violence from the left?

Clicked through a lefty blogger's entries just now--a guillotine decorated his page, Bush and Cheney's heads were on a razor blade, the Statue of Liberty holding up a cross had the international stop symbol through it, violent images abounded, lots of nasty f-ing words about conservatives, libertarians and Republicans, along with take back our Bill of Rights, yada, yada. Didn't see Sarah, but I'm sure he's recommending violence against her too, because that's just what the left does. Now, when similar nonsense appears on conservative websites, Keith Olbermann, whom this blogger seems to admire and imitate, gets all quivery and hot-crotched. I didn't leave a comment--he's entitled to his opinion and protected speech, even as he would deny it to others, and my opposite views certainly would only encourage him. Like it does here, when liberals think they know something I don't.
