We’re not cured of it. And it’s not just a matter of not being polite to say ‘nigger’ in public. That’s not the measure of whether racism still exists or not. It’s not just a matter of overt discrimination. Societies don’t overnight completely erase everything that happened 200 or 300 years prior.
It’s ironic that the right-wingers are worked up about President Obama using that word when they’re the ones who shrug (or retweet) when one of them uses it about the president.
It’s even more ironic that their twitterpation is proving the president’s point.
