Kennedy needs to be flogged in public, but conservatives still shouldn't resort to leftist grunge tactics.
How would you flog him, then? Ignore him?
This is effective treatment. Don't silence the man. Just remind him and his listeners, before every speech, that they're cooing and clapping over a murderer. Then leave.
Far better than the tactics of the left, which are intended to silence political dissent. I don't care if the SOB speaks to his accomplices. I just want them to know that they ARE accomplices, and will be judged, too.
