What we have now is a new breed of racists: Liberals who use the charge to ensure people are treated differently because of the color of their skin.
Sick old racists believed non-white people were inferior and deserved to be treated differently. The new racists still believe non-white people should be treated differently, just in a different, subtler way.
The way this new racism manifests itself is by making things people used to say about other Presidents racist when said about President Obama. What was once accepted criticism are now racist code words.
One of the earliest examples of this was the word regime.
When Rush Limbaugh used it in reference to the Obama administration, liberals were beside themselves. MSNBCs Chris Matthews said, I've never seen language like this in the American press
The use of the word 'regime' in American political parlance is unacceptable, and someone should tell [Limbaugh] to stop using it.
The only problem for Matthews, as Byron York pointed out, is A quick search of the Nexis database revealed more than 6,500 uses of the word "regime" to refer to the Bush administration since January 20, 2001, in the New York Times, Washington Post, MSNBC, and, yes, by Chris Matthews himself.
