edit: Since people are either willfully or otherwose are missing my point, this is a pro-russia, pro-fascist hate group, therefore we shouldn't give them the platform to spread their shit. this is not about me seeing their community or then causing issues accross other communities, it's about de-platforming fascists.
it's so you can have a conversation with such people about why you think it's bad for them to say that?
that assumes good faith on their behalf (or indeed yours) and there doesn't seem to be any of that.
