As long as that offense sits well with his constituency and generates ink in the process, it’s a win for Rush. It will remind his fans, current and lapsed, that there’s something going on worth listening to, and it will spike his ratings for sure.
Whether or not he apologizes or “clarifies.”
Note that this has nothing to do with what’s right and what’s ethical. Rush’s statements about Michael J. Fox are neither, and they’re pretty clearly crazy.
But Rush, as usual, is crazy like a fox.
If you’re going to Hell, go with high ratings.
