If I worked really hard on a long essay, and somebody called up my citations and they all said "Derek is dead wrong, and he didn't even call me when he misused my work," I would feel bad. I've felt that embarrassment before. It's an important feeling. Feeling embarrassed about getting something wrong is what tells you that you care about being right. The fact that the antitrust-housing left doesn't care when *their own sources* say they're full of shit is an important signal of something.
