If you were being logical, you would be claiming that the black middle class had not benefited from affirmative action, a claim that is absurd on its face. (You can't be claiming that I "need to read" more re Sowell. If you don't like what he said, you need to criticize him, not me.) But you're not being logical; you're being stupid and vindictive, in carrying a disagreement over from another thread that had nothing to do with this. Don't be so petty, cowardly, and dishonest.
I am very candid; to the point of rudeness; in your case, I have been patient. Sometimes, I hate myself.
