twoXchromosomes,or blackpeopletwitter are unapologetically bigoted subs which stay untouched.

Blackpeopletwitter is not bigoted, and definitely not unapologetically so.

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.

Things might have changed since I was forced to unsub due not being able to comment because I refused to prove to a few subreddit mods that i am indeed a person of color.

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

That lockdown happened for a brief period of time, and was not something the BPT community wanted in the first place.

Requiring users to send pictures of themselves in order to tag them black / not black and restricting posters in specific threads to black people or nonblacks that pass a test is absolutely 100% bigoted. It may be bigotry some are open to accept, but it's bigotry nonetheless.

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

How do you know?

And what about r/conservative?

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
