One of the issues I have with these threads about race is generalizations.
I work in a very diverse corporate environment. The blacks I work with are bright and hard-working.
Similarly two of the three black families that live nearby have a PhD as the head of the household. One is a medical doctor and the other is a well-known pharma researcher.
A combination of poor culture, lack of personal responsibility, broken families, and poverty appears to drive the behavior of some "urban" blacks.
The only thing I can state conclusively is that the educated blacks I described above disdain the thugs even more than I do.
