I think we need to realize that some generalizations are true. Blacks are more involved in crime than Whites, have higher rates of illegitimacy etc. That does not mean that we should not judge all people as individuals. It is a tough balancing act.
I don't think it should mean we are reflexively anti Black. I had to disagree with Chaim on the Jackie Robinson discussion. He said Robinson was not a bad guy but had hurt our culture by paving the way for Blacks in sports.
The problem with Blacks is not that some use their G-d given talent to excel in sports. If that was all they were doing it would be wonderful. The problem is too many are committing crimes, have unbelievable rates of illegitimacy and are anti Semitic.
