If you need see any evidence of how incredibly intolerent the left is of ideas that run counter to their own rhetoric, I have the evidence at hand. I think it was Charles Krauthammer who observed that the difference between Republicans and Democrats is that Republicans think Democrats are wrong, and Democrats think Republicans are evil.
The evidence at hand isn't Republican vs. Democrat, but it's idiological, and fits quite well in the Us vs. Them status that the Democrats have established in Congress. The writer is particularly dangerous as he's a very smart guy and a good writer (and for certain reasons should be toeing the Democrat line). Ergo he has been racking up rude, uninformed comments by the minute. Mostly just rude. And uninformed.
Anyway, it's a good read. Check it out at Michael Williams.
