When the Republicans were in power leftists delighted in screaming "racist" or "racism" every time a conservative made any utterance that was anything less than praiseworthy of any non-white American. The media generally ignored these asinine "racism" claims.
Now that the looters are in power (and how) we find Republicans starting to call leftists racists. The charges of racism from Republicans against Sotomayor are completely absurd. Obama's Supreme Court nominee has said nothing that I can find which would indicate that she feels that any one race is genetically or inherently superior to another. She may have shown just a bit of prejudice or bigotry or prejudice, but no racism.
Sure .. the left could get away with screaming racism at the drop of a hat. Why? Because the media wouldn't call them on it, that's why. A Democrat would scream "racism" and the media would remain silent. It's not going to be that way when a Republican calls a leftist a racist. The media is going to howl.
Due to rampant misuse the word has no meaning any more. So give it a rest. You're just giving the Obama-infatuated media something to use against the right.
