It's also OK for blacks to use the "F" word as every other word in a sentence - in public - without it being offensive, because if you call them out on it and tell them it's as offensive to you as the "N" word, they call you a racist honky cracker and get in your face to make you back down.
Some blacks are emboldened by the realization that the media and the courts (and Holder's Just Us Department) are on their side. As long as they call racisim, they can't lose. Luckily, the race card is wearing thin from overuse and people are starting to catch on to the trick.
These F-word using blacks will be grandly out of step when this screw up of an administration has been swept away by history. Suddenly it won’t be cool to (openly) play the fool.
