It wasn't just awkward demeanor. He actively made women feel unwelcome in the workplace and behaved unprofessionally over and over again.
> He held his positions at MIT, GNU, and the FSF for over thirty years, and in that time nobody accused him of coercion, unwanted touching, or verbal harassment
Yes, because of people like you, Geoff. When people like Stallman behave like they do and say the things they say they don't have to face the consequences because people don't want to speak up, because they're afraid of being called liars or censors. That's how authority figures and popular individuals keep getting away with it.
The second paragraph of the post is irrelevant and further proves the point. Stallman's contributions to free software don't excuse his conduct.
