Isaiah Washington, an actor on the TV show "Grey's Anatomy", called a fellow actor on that show a "faggot". Soon after, it was made known that Washington would be seeking "treatment and counseling". This was the incident to which Coulter was referring when she made her remarks at CPAC. It was meant to be a somewhat tongue-in-cheek reference to the the fact that now "rehab" is necessary for those who say stupid or ugly things.
Not knowing the show or what Washington said, Coulter's comments wouldn't have made sense to me. Lots of people didn't get the reference either. For many it wouldn't have made a difference - the use of the other "F" word is what got all the attention.
Coulter is merely a commentator and author. Being acerbic and sometimes controversial is her thing. She knows how to push buttons as evidenced by the replies here. However, she is not the official spokeswoman for the Republican party. She only goes where she is invited. If Republicans feel that somehow her comments will reflect poorly on them, I suspect they'll stop inviting her.
I find this interesting: on another thread in this forum, regarding the Kent State professor who is a cheerleader for radical muslim jihad, many posters, while disagreeing with his political position, defended his right to free speech. On this thread, though, there is so much more outrage and condemnation over the use of ONE WORD. Someone even wondered how "she was able to get away with it". Ugly as it is, that single word doesn't come close to being anywhere as harmful as what that professor spews day after day.
Selective moral outrage.
