The majority of conservatives are not nazis even if they unknowingly support them. It does makes sense that nazis are looking for a home and colonized offshoots like lemmy though as the explicit ones would be forced from mainstream outlets.

Obviously there is a line there, where do you draw it? From banning out and out nazis, to what? Who says who is a nazi, or a fascist?

We should have a clear set of rules, and violations, or censoring, should go through a process ending in a jury trial of users before any final decision is made. Not only would it be fun to run such jury trials on violations, and give a sense of community, but it would prevent moderators and developers deciding for us what we can see and prevent abuses of their power, and prevent government and business interests getting their hooks into the moderation.

In the case of banning instances idk about that even, my instance doesn't block any instances and I've seen no nazis. Even if I did, so what, I could avoid them, same as I do with tankies. It's better to be able to see what they are doing anyway, insight is valuable at times. The instance could have a banner explaining they are condemned by the other instances, where you have to affirmatively click on it like a nsfw post.

What about people critical of Israel? Israel's superfans insist it's bigotry to not support their final solution against their others, to question them forcing millions of people into ghettos. Are we to censor anyone disputing such narratives because bigotry is alleged? Because they equate criticism of their policies as naziism, quite literally, while themselves being nazis of a new sort. The bad (worse) guys always accuse their victims/opponents of doing what they are doing. Why should developers and site administrators decide truth on their own?

I do not see what good it does banning instances in the first place. You think your own users are going to become nazis after seeing their posts? To protect their weak minds from wrongthink? It doesn't really work like that, and people not being exposed to it can make it more likely they get seduced to it not less. And it's not in the best traditions of western culture to censor viewpoints as such.
