Turns out that the Martin Kramer column Stan linked to makes exactly the point I was making — and then some. Kramer writes:

All this leaves one wondering just what’s going on in Khalidi’s head. The answer, of course, is that Khalidi is a radical. If you’re a campus radical, you dismiss anyone who isn’t totally with you as a “conservative” or an “extreme conservative.” You may be surrounded by people who view themselves as liberals, who opposed the Iraq war, who believe in “soft power.” But because they won’t denounce America as a resurrected empire or rally to the likes of Joseph Massad, you cast them all as “conservatives” who are part of the problem.

BTW:For people interested in the subject of radical hatred of liberals in the academy, I seem to recall a great discussion of the subject in Alan Brinkley’s Liberalism and its Discontents but I can’t find my copy.
