Hi Colin
I am hesitant to comment because of the nature of my job.
I will say that Singleton alone created a hostile environment at the session I attended, where it was assumed that all whites were racist and had no business teaching black kids.
I have twenty years as a coach and teacher in black schools, so it was a surprise to me that I was racist and unfit to coach black kids. It was an insult a minute, that prompted "Amen" from some of the blacks in attendance.
I, along with the majority of whites I spoke with, were completely insulted, and this was the intent, as Singleton strode to the microphone at the beginning and said he was there to "make us uncomfortable." It was ridiculous and lasted for three hours. Black coworkers were taught to look upon their white coworkers with a suspicious eye. A mess. Period.
I won't offer much more comment. It was a disaster though. But it has made Singleton rich, as he charges hundreds of thousands of dollars to do this berating of whites.
