You're willing to give him the benefit of the doubt because you're a fan of his work and his ideologies in other spaces. Which makes sense, I dig it.
For myself, I'd rather not expend the mental gymnastics. If RMS had ever wanted to set the record straight, he could have. If he isn't willing to clarify, personally I'm uninterested in attempting to do it for him, and inclined to assume this (like his other writing) is direct and unambiguous.
(Edit, to add:) And to reinforce my previous point: sometimes the damage one's words do can't easily be undone, and treating everything like it's a philosophical debate and not someone telling us who they are may reinforce that harm.
