I don't think a racial slur is ever a good thing. But I think there is a difference between using a slur publicly (in print or televised) and using one in a private conversation with a family member. I don't know if he's a racist or not. But I'll tell you this much...that conversation was private. I don't think anyone had the right to secretly tape it and sell it to the Enquirer. I don't know ANYONE who has not said something in private that would not publicly humiliate them were it made known. I don't endorse racial slurs or excuse them. And I do I know what it's like to be on the receiving end of a slur like that. But I think if some one makes that slur privately to a family member, and doesn't go public with it, they are only making themselves look bad and not the person or race in which the slur is intended. Whereas going public with a slur, in some situations, is more of a public endorsement of racism. THAT is just stupid and you should have your show canceled if you do that.
I sure don't want to see people punished for something they say in private to a trusted family member. There's just too much of a "Big Brother" feel to it knowing our private conversations with some one we trust can result in the loss of everything we have worked for most of our lives.
