That qualifies as slander as I understand it and he should have to answer for it in a court of law. Moreover, he used the public airwaves to deliver his hateful statements and IMHO should now be deprived of such as a result.
That's exactly my point. "Free Speech" is peoples' protection from the government. The lack of "Responsible Speech" is dealt with by public opinion, sponsors dropping or coming on board, or a court of law seeking redress/equity.
But Rush should not be "deprived of such" by any government authority.
