Extreme short version is that the "rationalist" cult known as LessWrong/MIRI has a founder and leader that is rather open about his mind control fetish... other people's minds, of course. In real life he drugs and hypnotizes his sexual partners yet wraps all the coercive and rapey behavior in so much jargon and techbro slang that it sounds like something other than drugging and brainwashing people so he can violate them.
