a. i think she was too young to appear willing

That could be true. It's a valid point.

b. he’s staying at this weird rich dude’s island and suddenly a very young woman wants to have sex and you don’t think she’s cooerced?

It's certainly weird, but I think there is some chance that he didn't know.

but the other term would be statuary rape, which still implies violence…

I don't know much about that, but according to Wikipedia, it's usually not connected to violence: https://en.wikipedia.org/wiki/Statutory_rape. Statutory rape is a legal term, it's not actually the same thing as rape. See, this is another example of what Richard was talking about.

given his position, i don’t think it’s responsible to try to claim pedophilia might be moral, if the child is “consenting”, etc… like sure, it’s okay to discuss ideas… but he acted as if he knew for sure there’s no evidence that it’s harmful…

It would be better if he didn't have stupid or weird opinions, but he is a philosopher, so he thinks and talks about ethics and stuff like that all of his life. Especially on his blog - you can check stallman.org. He is even against using paid toilets. I don't know where he got the idea that a child could consent or that it wasn't harmful, but I've seen some pedo say online that there is some research, which allegedly proves that. So I assume they just cherry pick to find something that supports their claims, but then they of course ignore all of the overwhelming evidence against it. This often happens in pseudoscience. So maybe he read something stupid like that, I don't know.

i don’t think he should be punished, but i don’t think he should be accepted as a spokesperson, figurehead, or leader…

But if he wasn't who he is, I don't know if he would have created the Free Software movement. Many people today still think that it's a radical idea that users should have rights, which nobody should be able to take away from them. I think we need people like him in our society. I also don't know anyone else who has been fighting for this for 40 years refusing to make compromises on people's freedom (unlike Linus Torvalds for example). To this day he still travels the world and gives talks about Free Software in multiple languages.

i felt the same way about Stallman as i did about Allen Ginsberg when i found out he was a pedo…

But Richard Stallman is not a pedo.
