Malevolent_USB_Drive: I personally am fairly happy to see the ban, unfortunately I don't believe the ban had much to do with their white nationalism or antisemitism, my understanding is that the biggest contributor to their ban was a highly upvoted, stickied post called "Open season on leftists" which basically had a list of various leftists on reddit and encouraged "retaliation" against them, of which the details were left unspoken.
Furthermore, there was also an issue with a website they apparently kept linking to which offered a bounty on said leftists, which even after it being soft banned from reddit, they continued to approve and post to.
The point of all of this is that I don't believe that their ban had anything to do with their partisan views, I believe it had everything to do with them leading a witch hunt against those with views they disagree with.
This tells me that so long as other partisan political subreddits keep away from engaging in doxxing, harassment, blatant incitement to violence, and witch hunts against individuals, that they can be as extreme as they like without repercussion from the admins.
InOranAsElsewhere: The admins were being consistent. Given the ban was for issues with personal information (e.g., the bounty to find the guy who punched Richard Spencer), I think it's a reminder for all subs to stay within the site wide rules. People will try to say it was ideology, but that's just spinning a narrative. Unfortunately, with the sub banned, it's harder to pull up proof of the reason.
As far as other subs go, I think if they stay within the rules, this doesn't spell doom for them at all. Any time a fringe political sub gets banned, they try to frame it as the admins acting ideologically. But if you dig deeper, flagrant rule violations were occurring. Unfortunately, lies travel faster.
Prince_Kropotkin: /r/altright needed to go; they were compiling lists of individual Redditors, linking to crowdsourced doxxed sites, and so on. That stuff alone gave the admins cause to ban them under sitewite rules. But they were also nothing more than a memey neo-Nazi den filled with edginess and slurs - why the hell keep that around?
I don't think other political subs are in danger unless they insist on breaking sitewide rules or are so legendarily awful that they make the New York Times (we'll see about /r/anarchism's new public take on attacking everyone who disagrees with them, I guess).
