Sowell's great and a credit to his race but his economic prowess doesn't change tens of thousands of years of evolutionary differences. When blacks are 50 times as likely as whites to have the 2 repeat allele of the MAOA gene which gives those who have it a heightened fight or flight response and makes them far more prone to impulsive, irresponsible, and aggressive behavior, it makes sense to be wary of blacks you don't know because they're much more likely to hurt or kill you. Depending on the situation you're in that might not matter or might be a life or death decision. When you tell women that black men and white men are the same, and that causes more of them to date black men who are twice as likely to commit rape, three times as likely to commit assault, four times as likely to abandon their kids, five times as likely to have AIDS, and ten times as likely to commit murder as white men, all those extra single mother rape victims with AIDS are on you, not me.
