I would correct that.
Nazis didn't wholly think that. Not all races where "worthy of extermination". For example, black people in the Reich were largely ignored as a non-problem and left to their own devices and people from the Middle-East were recruited as part of the armed forces. "Honorary Aryan" is a thing they did too when someone proved to be useful (Japanese have been declared as such). Just a short history FYI.
Racism is the more correct term, believing any human inferoir based on their race, and some racists demand extermination. Nazis are a specific subgroup of racists.
There's bad in both sets, which is why banning 1 group could have an effect on the other 2, eventually.
There are no good Nazis. Sure there were some Nazis in WWII that were Nazis because they were German soldiers and not necessarily because they wanted to exterminate Jews and gypsies, so some of them did good things (not in the name of the Nazis but because they were not entirely evil people) but anyone claiming to be a Nazi today is doing so because they believe in Nazism ideologically and everything that goes into with it.
And yet, part of what makes you "wrong" to oppose speech of particular groups is that you are just as bad as them. That's a judgment of the "wrongness" of a particular ideology, being directly appealed to, to justify a position on free speech.
For some reason that's supposedly not a slippery slope toward widening the scope of "free speech" to include things destructive of democracy.
But if you confront them with the slippery slope of equal logical validity which supports the opposing argument, suddenly they're mindful of the dangers of slippery slope arguments.
Of course your definitions are loose and biased, you know that. You're just venting and telling people you don't care if you're wrong.
Look, I think Nazism is wrong, I think cops should stop shooting black people for no reason, and I don't really know what "Antifa" is. But I think all of these groups should be able to have subreddits.
I could argue about definition here, and based on your own definitions, "Antifa" might be advocating violence. That aside, the real issue here is that this whole thing seems dishonest to me.
Reddit is banning stuff that generates bad PR. They're banning things that aren't mainstream and things that could be portrayed as advocating/glorifying violence. They aren't going to ban a subreddit for advocating war with North Korea/X country. They aren't going to ban a subreddit for encouraging people to beat up Nazis.
Reddit can do what they like, but I think it's a bad call.
In the end, my personal opinion is that any form of inciting violence against civilians should be banned, regardless of what your cause is and how much more "in the right" you are than Nazis on a relative scale, which is a pretty low bar.
Nazism - The belief ( on pseudoscience i may add )that other races ( a term that has no scientific basis ) are only worthy of extermination ( death, MDK )
BLM - The belief ( on experiences of some in society ), that Black people are not treated the same in their interactions with the government. Main vehicle, in your face protests.
Antifa - an aggressive anti-hate group ( whose tactics, in the view of some, seem to make them a violent group ). The anti-nazis if you will.
Really? Do these things seem REMOTELY equal?
cue in the nitpicking about my definitions...
PS: to be perfectly clear/blunt, since it seems as I suspected people started nitpicking... One group calls for the extermination of HUMAN BEINGS.. the other calls for the extermination of IDEOLOGY... now see the difference?
free speech DOES NOT and HAS NEVER given you the right to call for the extermination of others... that is as clear cut case of "not protected by free speech" as there is.
and yes.. if you take on the name of "nazi" or "national socialism", well, you don't get to redefine those terms in a "wink wink" manner.
