Let ME repeat: no one here said either is "OK," but the contexts are very different. Why is that so hard to understand?
When African-Americans are a majority and have enslaved whites for 400 years, then we'll talk about how "all racism" is the same.
In the meantime, the difference is power. And why Bill Maher mocking the President (even if you think the satire is wrongheaded) is very different than wealthy Rush Limbaugh mocking a homeless man.
Jokes and derogatory remarks directed at the powerFUL is satire, a non-violent way of defusing a very real threat. Jokes and derogatory remarks directed at the relatively powerLESS is just, plain bullying, and that is cruel.
And while we're on the subject, why should I care that African-American rappers are allowed (in some social contexts) to say "






" and I am not? I have no business using that word in any case, so how does the "double standard" hurt me?
