What he said was not as much of a problem as the capacity in which he said it and the forum on which he said it. If the president of the PGA is going to directly criticize a professional golfer and use slang derogatory terms, he probably shouldn't make them public to every person on planet earth.
With that being said, I can't believe how badly the PGA overreacted. Political correctness nazis ruin people's lives on a daily basis -- this is just a mainstream example. (Now they're going to come hunt me down because I used the word Nazi out of context).
