I'm gonna be annoying and I know it, but I really hate that people equate the far left and the far right. What does the far left want? Destroy capitalism. What does the far right want? Kill all queer people and then some. For some people, the opposite of Nazism is Communism when these barely have anything to do with each other.
The far left can be annoying, sure. But in the end, the vast majority of them are not actively trying to justify mass murder. That's a key difference. Also, one has dramatically more influence then the other. So the question should be:
Should the far right be an allowed part of Lemmy's fediverse?
Which is a misunderstanding of the fediverse I think. We can't forbid them to be anywhere on an open source and defedrated platform. We can however, ask if they should be tolerated? And that's up to the various servers to decide.
Beehaw already has a stance on it, though: No. Hence the recent defederation. And I agree. Fuck Nazis.
