You and I are on the same page! On a given day, there are AT LEAST a half a dozen of these black on white crimes brought to our attention here on FR. Many of them end with the death of the perpetrator, so you just have to wonder what drives more and more blacks to take these actions. I am betting that the “race baters” like the “two reverends” have a lot to do with it. There seems to be the notion that the “reverends” have given the perps the green light that it's “within your rights as an aggrieved minority” to abuse white people. Fortunately, white folks have, in most cases, figured out what they need to do to be prepared to defend themselves.
We have an excellent example in front of us. What drove Trayvon Martin to attack Zimmerman? I have my own ideas.
