The admins have taken a stance where this should be a safe space and those being insulted/harassed/discriminated against are welcome to respond in kind. The most important part is to report it so the mods/admins can review and take action as needed.

While it may not be nice to tell nazi punks to fuck off, it will ultimately make for a nicer community if they do - we don't mind community members saying "hey, this isn't cool" in whatever manner they feel necessary.

without downvotes as a tool against crap like that, what have we got? is it against our instance’s “be nice” policy to tell nazi punks to fuck off?

nope! we're not going to ban for telling a TERF or nazi to eat shit or whatever. we as admins do try to be nice where possible, but you as a user really aren't obligated to be because that's dumb lol. you can also report it to us and in general we dispatch users who are like that as possible (although sidenote: if it's a post off-instance and you report it, unless the user is really, really bad we probably won't do anything immediately because we just can't keep an eye on every possible bad actor.)
