The thing that always bothers me about the "it's just one person" defense is... well, what about the other prominent members of the community? How do they feel about this person's beliefs and behavior?
I work on Xfce in my spare time with a small group of other developers from around the world, and if I learned that one of them was a neo-nazi, I would immediately call for them to be expelled from the community. If the other maintainers refused, I would step down and leave the community myself.
To me, any other response would be tolerating and accepting neo-nazism, to the point that I would assume and expect outsiders would suspect the entire development team is ok with neo-nazism. None of that is ok in my book.

I think FRIGN is odious but my judgment is that a gross edgy joke (the hostname) and one reference to "cultural marxism"* isn't sufficient to call someone a neo-nazi. Well, more importantly, believing it isn't sufficient (as I do, and I suspect the suckless people do) does not mean people like me or the suckless people are, as you word it, "tolerating or accepting neo-nazism".
*Despite Wikipedia's only page on cultural marxism being a redirect to "Cultural Marxism anti-semitic far-right conspiracy theory", it is not unusual to rail against cultural marxism in normal conservative circles, including respectable anti-Trump anti-anti-semitic circles like National Review and Tablet. See for example https://www.tabletmag.com/sections/news/articles/just-becaus... ; but I don't want to veer this thread into off-topicness, only to provide evidence that complaining about cultural marxism doesn't make someone a neo-nazi.
