Query: This book is tripe

Bill Cosby speaks the truth and then you have people like Dyson trying to shoot him down for speaking that truth. As an educated black Ph.D., I find Dyson's book offensive to intelligent people who expect more from themselves. Dyson should use his time more wisely than to shoot down Bill Cosby for speaking a truth that more black people need to hear.
