As a counterexample? Does he fit here? Does he speak mostly on politics rather than other topics? Then again, his political beliefs/actions are so polarizing that maybe it's hard to separate them from his work in other areas (somewhat akin to what the organizers of Strangeloop claim in their case.)
Does Noam Chomsky get heat for his political views? I was amused when I realized the Chomsky I'd heard about in CS classes was the same person I'd read about in political news. I guess his views are more palatable to the people criticizing Mr. Yarvin.
