Stay focused, birther. I know, an oxymoron The OP asked if flash mobs were a black thing. I presume it was rhetorical because no one is stupid enuf to attribute an all or none statement to a group of 12 million people. So, I responded in kind. I see that you are no more intelligent, but you are a birther also, so it makes sense actually.
So being effective killers is a competent thing for a WASP. Nice. Killing seems to be a white thing, white people are very good at it. Are you a killer, confused one?
Again, absolutes. That is the trouble with primitive thinkers. Lack of differentiation. My neighborhood happens to be nearly 50/50.
