Stallman was pressured to resign from the board and MIT because of some of these controversies:
- Jeffrey Epstein coerced one of his victims to have sex with Marvin Minsky. In an online thread, Stallman argued that this might not be sexual assault if Minsky didn't realize she was coerced.
- 10 years ago, Stallman claimed that 14 year olds are old enough to consent to sex and it's not pedophilia. He since retracted this claim
- He is generally very weird and doesn't have etiquite. For example, he was invited to a fancy restaurant and then pranced around the tables because he wanted to dance
Overall, Stallman is very unaware of societal expectations, so sometimes he says things ranging from non-PC to outright sexist, albeit unintentionally.
