Laws don't decide things anymore, outrage PR + a potential/real wave of lawsuits do.

If you think about it, that doesn't seem too bad until you realize a lot of of the negative PR is manufactured by only taking part of the story and using it out of context. Sometimes even approaching propaganda or conspiracies.

The few that got closed regularly went out of their way to brigade other subs. But the rest of them is happily flourishing there.

What evidence do you have for this accusation?

It may come across that way to you, but black people talking about their actual experiences caused by non-black people in a way that makes a non-black uncomfortable does not mean it’s bigoted.

Around that time, many if not all of the threads ended up being closed due to the the dramatic arguments that formed when users posted political/racial commentary to the sub; which is to be expected. I believe the real problem was when comments from users who portrayed themselves as POC felt their voices were less pronounced due to the downvotes and negative replies. Understandable

So they decided to lock the sub down for anyone except those who accepts a segregated bubble and willingness to prove their "blackness" in order to post an opinion

And even ignoring that, Reddit would never allow the reverse to happen.

Each sub has a wildly different number of posts, moderation results, reporting of violations, and moderation response times. Unless there is clear evidence of intent making the claim that Reddit makes decisions based on political bias is wrong
