Not Crossing Limbaugh

Of course she won't:

PALIN: I didn’t hear Rush Limbaugh calling a group of people whom he did not agree with ‘f-ing retards’ and we did know that Rahm Emanuel has been reported, did say that. there is a big difference there. Again, name-calling, using language that is insensitive, by anyone, male, female, Republican, Democrat, is unnecessary. It’s inappropriate. Let’s all just grow up.

So how about Coulter, Ms Fox Contributor only being interviewed on Fox? Or is it okay to call the first female Speaker of the House "mentally retarded"?
