At various law schools, student groups organize what are sometimes called “canned immunity” drives — if students donate canned food that will end up going to a soup kitchen or some similar charity, the professors agree not to call on them. I’ve always been vaguely uneasy about this, but I’m not sure whether I should be.

I’ve never liked that either — I don’ think of being called on in class as a punishment, or being ignored in class as a reward.
