>lots of other communities are allowed to exist despite having much more and more overt bigotry including celebrations of political violence

I would argue that was what TD was until very recently.

Maybe. Those other ones aren't banned though while TD was. Combined with the fact that their new rules explicitly allow for harassment of majority identity groups, I'd say this isn't a good move.

TD wasn't either until just now ... maybe those 'others' will be tomorrow?

I'm not sure the timing of non specific sub banning really means anything.

That's the point. Other communities are worse than TD and go reprimanded. And it's not just communities like TD; people are canceled, terminated, etc for completely not racist offenses such as "making an OK symbol by accident" or "standing next to a woman who wrongly suggested a minority person was vandalizing a store" or "citing a prominent Black academic's research on nonviolent-vs-violent protests" or "publishing an interview wherein a Black man says that he wishes there was more concern for crime problems in predominately Black communities", or "publishing an op ed from a US senator that expresses a viewpoint shared by more than 50% of the US public", or etc. Meanwhile people can go on years-long racist tirades on Twitter and be promoted into the NYT or say things like "literally all members of $RACE are irredeemably evil" in a book and hit the top of the Amazon and NYT best-sellers list and get diversity consulting gigs all over the country. There aren't words to describe how far beyond parody these double standards have become.

EDIT: That's a lot of downvotes. I'd be really interested to hear what specifically people disagree with. Do you contest my assertion that a double standard exists? Or maybe you don't agree with my negative characterization of TD? Or do you contest that the implication that double standards (in general or this one in particular) is morally wrong? Let's talk about it (leave the downvotes by all means, but let's have a productive discussion).

Honestly it's hard to figure out what even you're saying.

That reads more like a general ideology of persicution you're describing that you think is true ... rather than anything about what I said.

I said that TD was reprimanded for doing things that were at worst on par with other groups. You said “that sounds like TD up until recently”. I said “That’s the point” and went into more detail about my original claim (namely that the double standard targets not only conservatives but all but the most extreme leftists).

As for “ideology of persecution”, that could apply to anyone citing examples of a double standard. At best it begs the question.
