I am not affiliated with either MIT or the FSF, so my social norms have little to do with it.

Anyway, you're playing the dumb little game that people like to play with this topic: "If you're so 'tolerant' why won't you tolerate people saying offensive shit?"

And you've heard the answer a million times, I bet, you just won't accept it: Because it silences higher-quality diverse voices and "asshole who says repellent things" is already a wildly overrepresented class of person in the tech industry.
