Cosby was preaching the party line until just recently, then he suddenly saw the light. When he did black leaders pack hunted him and instigated a scandal to keep him busy. Better late than never, but he is no hero IMHO.
Give me a break about bad schools. If a teacher could teach in crime ridden schools, you would get teachers to take the positions there. Those employed are called teachers but are really baby sitters for the delinquent.
IMHO the problem is with the mothers who are raising these children. Forget the fathers, they are largely absent. Someone perpetuates the hate, the victimhood, etc. and it is the mothers/head of households.
