Well, I dunno. Some (most) of these people seem like pretty crappy/creepy people. There is a point to not giving an outsized voice to social deviants and racists even if they are genius at turning a phrase. These examples have already had their voice, however, and some, like Darwin, are loud. And some, like Darwin, are important. And others not. I am a fan of freedom of speech. I am a foe of hate speech. 'Tis a predicament.
