@chrism summing up, it seems the worst of the two opposite "camps": the SJW are taking control of the community and the current leaders are under attack; current NixOS moderators and leaders are not able to manage/moderate the community in an effective way (or at least the SJW part of it).

I hope they find a clear and effective re-organization, because doing so: there will be a clear alignment of the community, with less distractions; if some group do not accept some choices, they can fork (in the positive sense of the word).

Regarding the CoC, IMHO the good enough approach is this https://www.gnu.org/philosophy/kind-communication.en.html

Regarding community management, I should study how other communities are organized. I suspect it is more difficult than coding... So maximum respect for the effort.
