All Barkley Sharpton Jackson Cosby etc are doing is exploiting a market.
A market created and fuelled by the white media establishment and its morbid fascination (or is it fear) of other races.
This is a very big market btw, it generates copy judging by the number of posts that we get about it on here, a sub-board at the ass end of the internet.
You won't find the American establishment media talking about Jews in this manner, or the Germans, or the Japanese or the Chinese etc on anywhere near the same kind of scale.
Any people involved in extreme politics concerning other races' (for want of a better description) tend to be ignored by the media for the morons that they are.
It's pretty much a black dudes media phenomenon, although the media is pushing Islamics into the spotlight again (like they did back in the 60s during the Muhammed Ali period).
