IMO, it's a way to keep racism alive and even make it worse, in their mind (at least a good amount of them)....
think about it, if a neighborhood was full of crime and the response to deal with that was, there's no crime or criminals, let's just stop talking about it and the issue (crime in my example), will go away....let the neighborhood police itself without anyone to watch over it.....
if that's done, what would any logical person, think is going to happen to the crime in the neighborhood?....hello.
That's why I think folks like Limbaugh, Hannity and Beck, go after anyone who even mentions race at all in anything and really craps on those that do, when, it could very well be an issue (like the % of blacks that are unemployed in the US, vs the % of whites in the US that are unemployed)....
they figure if no one talks about it, and does anything about it, it will "just go away", when they, wink, wink, at the same time, since they know, down inside, that's not realistic.
of course, conservatives will scream about reverse racism (against whites, without blinking an eye)....go figure....
bring on the haters.....
