Good point. But we all know how that works. It's only racism if you're white.
Stupid point but of course I wouldn't expect you to know it
There are examples of blacks being fired (and Sterling wasn't fired but just banned by an organization of which he was a member).
Hugh Douglas was fired from ESPN for making racist comments
Joe Williams, White House correspondent for Politico was fired for making racial comments about Romney
Those two just came to mind immediately but I'm sure I can find more
