you will find that not allowing Nazis and the likes into your community generally ties it together, rather than cuts it apart.
It isn't the case that even if everyone agrees on the BLM, Trans rights, and the outcome of WWII will agree on future issues of the day. Thier stance sets up an expectation that the language should have an official position on these topics.
I even gave an example.
A community that fosters professionalism rather than explicit ideology won't have this problem.
It's pretty much the same as don't enter into professional relations with the local mafia, it's mostly a matter of scale and available weaponry.
If I recruit you into my organisation I trust that you will not bring in criminals into our enterprise. I would not hire you if I thought that it could bring attention from the fuzz or expose us to extortion.
People who want to stop people from dying by taking the problem seriously: "nazis". :(
Says more about you than the project.
