Entertainers have a right to their views and a right to speak their mind....they very often work that into their art and performance...that's the way it is.....I think Ted Nugent is the biggest asshole in Rock but I overlook his crap when he comes to town....because he rocks.
The right becries a Linda Ronstadt or a Dixie Chick, but takes a marginal shitkicker like Toby Keith and turns him multiplatinum because he writes a song about putting his boot in someones ass, and puts red white and blue in the title which appeals to some chronic pathological need to be John Wayne. Exactly how many big hits has Lee Greenwood had besides God Bless The USA?
The rules only apply to the person you don't like, whatever side you're on.
Personally I could care less.
