It's 100% a problem, for multiple reasons. First and foremost, it's racist, so it's already inherently a problem for that reason alone.

Nothing is "inherently" anything. What makes, for example, anti-black (as contrary to anti-white) racism bad in spaces like this? It furthers the psychological harm caused by the racist material conditions of white-supremacist society and normalizes these conditions. Racist rhetoric is part of the superstructural justification for these conditions that makes the oppressor feel superior and the oppressed feel inferior and like they deserve it. This contradiction does not exist for white people and that is why anti-white racism effectively does not exist, except maybe beyond a limited level in inter-personal relationships. It might make individual white people feel a little bad but it has no material backing.

But it's also a problem because your [hexbear's] moralistic self-righteousness

I'm not the one pearl-clutching over anti-white racism.

combined with your [hexbear's] obvious hypocrisy gives people opposed to your ideals that much more ammunition (and of course you don't care about that, but that itself is also part of the hexbear problem).

This issue doesn't really give anyone "more ammunition" against us. Part of the reason we do keep these kinds of jokes around (besides being funny) is because it tends to out reactionaries (like how you are being right now).

And the worst part is that, as with so many of hexbear's problems, there's no reason for it. It's such an easy problem to fix, and would give an instance like hexbear that supposedly prides itself on its inclusivity such a huge boost in credibility.

I'm pretty sure most of the people making "cracker" jokes on here are white themselves. I don't think Hexbear is known as the "anti-white" instance lol

And sure, I get the importance of having a place where you can feel comfortable and meme hyperbolically about problems you feel are important, and about the people who don't agree with you. That seems to be the direction that most hexbears seem to want to go.

Yeah, I mean that's pretty much what Hexbear is. I don't think anyone here would want to be "morally-unimpeachable leaders" or even to what end that would be.
