Certain to cause some outrage:
Critical theory should be treated more like creationism in public schools than scholarship: an unfalsifiable form of religion, preferably banned outright, but if not, always accompanied by Darwin. – Andrew Sullivan, The Weekly Dish (paywall)
Of course, then you’d have to prove that it’s unfalsifiable, and then teach why that’s bad. I’m not sure the first point is yet established, but so far this is an interesting start.
