Tim Wise has a great essay on this topic:
On White Pride and Other Delusions
some good quotes from it:
"As for racial slurs, while it is certainly fair to point out that their use is always inappropriate, no matter whom they're directed against, to think that a term like hillbilly is truly equivalent to those used against people of color, like "nigger," "spic," "raghead," or "chink," requires one to exhibit a profound ignorance of history. "
"After all, every month has been white history month, even if they weren't called that. White history has been made the normative history, the default position, and when your narrative is taken as the norm--indeed, when it gets to be viewed as synonymous with American history--the need to racially designate its origins is obviously a less pressing concern. White folks' contributions have never been ignored, diminished or overlooked."
"To have a White Entertainment Television would ignore that whites already predominate on most all existing networks, and that shows pegged to people of color are few and far between, and usually limited to a handful of smaller networks and cable outlets."
