How can you improve if you can't take criticism?

Well, more confirmation of my theory that Conservatives see themselves more as a complete alternative to the supposedly "liberal" worldview. David Frum, who seems to be one of the shrinking number of generally sensible Conservatives, has been forced out of the American Enterprise Institute according to the New York Times. It sounds like the rather sensible, realistic, and moderate critique he was giving of the Republican's stance on health care may have been too much for the AEI. Be sure to link through to some of the linked articles from Frum, in any rational world this wouldn't be a bridge too far.
