About 8 zillion times I’ve criticized liberals and the left for not having more of an internal debate on first principles. They are much to interested in strategy and winning and not enough interested on what they actually should believe. This, of course, is a sweeping generalization. But I think it’s a fair one. If you want a sense of how hard it is to have such a debate, take a look at this post by Amy Sullivan, who seems to be trying very hard to have a serious conversation with her comrades.
