Well, I haven’t caught up on my recent issues of Radical History Review, but there is one sense in which Khalidi could be right. There are a lot of radical professors who in fact hate liberals and see liberalism as a form of fellow-travelling conservatism. My guess this isn’t what he meant, but it is true that the academy is probably the last major American institution — with the exception of a few magazines — where significant numbers of leftists still maintain there is a major difference between left and liberal in an intellectually serious way.
