That being said: I do agree that some of the statements made in the past were tasteless, and I am disappointed that he did so. Yet when reading his own texts like https://stallman.org/articles/necessary-changes.html, I have to either conclude that he agrees but has made mistakes or is himself lying.
Another thing might be that I have only had contact with him via Email. Perhaps he is different in person, that I cannot say.
Yes, but not every loss is equal, and in a changing world, growing groups will eventually reach a point where not everyone who wants to play will agree on the same ethics, which will lead to someone feeling unappreciated.
If I had the choice between losing a F/L/OSS contributor who has spend their life writing highly influential software and a F/L/OSS contributor who opened a 200-line-Python script once, half a year ago, I know who I would consider less of a loss.
I guess you could try this out empirically, by creating a throwaway Email address and sending him a dry, technical question under a female name, and see how he responds.
To be clear, I have no idea as to the truth of this situation, I am just saying the criteria to judge it must be different than that, especially because creeps do their best to hide their creepiness to the general world.
Nobody would have guessed, also that you are male too. I really do believe that you have a problem with racism and sexism, but it won't be solved by accusing others.
> So as far as I know [...] quite some apparently have
You should not regurgitate these rumors without further evidence. I can imagine someone like Stallmann being awkward with women and maybe some of the accusations are true. That is certainly no reason to prosecute him like this. Not your job to do so, work on yourself instead. There is enough to do here and then you can lead by example.
> There is a reason, why the free software movement is largely dominated by men
Certainly not a fault of Stallman. Some women also do not like men trying to make their mark everywhere and these easy accusations of sexism or discrimination feel a bit like that. Pretty sure you won't find the "fault" for that in others.
