Rush is sick because he called a slut a slut? Did you bump your head before you wrote that?
Let me ask you something, Clint. If your child called a loose woman a "slut" in public and in your presence, would you praise that child, or would you swat that child's butt and tell him/her to use better manners next time?
If you would praise such stupid exhibition of anger and self-righteousness, then YOU are the one who has a seriously bumped head.
Rush screwed up in the LANGUAGE that he used, it was for something his own mother would probably have frowned on (she'd probably have pointed out he could have said the same thing a different way in a more gentlemanly and Christian manner), and the consequences are pretty serious.
