I may shock you all on this one, but boycott him if it your desire to do so. I boycott things that offend me.
Protesting Rush, though? That's just ridiculous. I'm not walking around protesting Tom Daschle (apples and oranges since Daschle can affect my life much more directly- the guy wields power not a microphone), Alan Colmes, or Gloria Allred. What's the point?
