The only questionable thing he did was try to rationalise pedophilia, which he has since changed his mind about. Given that he's clearly _not all there in the head_ (i.e neurodiverse) and assuming he hasn't tried to access child pornography or similar I couldn't care less. All of the other accusations against him are nonsense[0] and all center around unsubstantiated rumors of him being a "creep." People being anti-Stallman is insane to me considering how much he has contributed and advocates for not only free software but also gender equality.
