The Washington Post people won't say anything, they printed the cartoon, and Oliphant is one of theirs.
They wouldn't run cartoons of Jesse Jackson or Al Sharpton, of course, because they're such useful idiots. It's the patronizing, "Pat 'em on their heads, and keep 'em voting" white Democratic mentality.
I think we need to contact some of their advertisers and make them aware they are supporting racism:
Intel
British Airways
Microsoft
Neiman Marcus
University of Maryland
Dell
