Why is r/4bmovement not taken down?

Important: I am SPECIFICALLY talking about the subreddit, not the movement which I support

Hi so basically I’m a guy, and I did a little scrolling on there and found some crazy stuff, one example having someone ask “are there any good men?” And someone responded with “my dad” to which another commenter responded “he was probably a piece of shit male that hid it well” now obviously there are more examples, which I do have screenshots of, and I understand it’s likely a trauma thing but that sub seems incredibly sexist and i want to know why it’s okay?

(Sorry for the tangent)
