Posting a blacked out screenshot and saying "Ada made me do it" is just weird. You didn't even leave a description. All we see is that you got a DM and there are a bunch of scribbles over it, this is a nothing burger. It being pinned to the top of the community is weird. If you had posted the actual screenshot and made an actual point to what they said and didn't use slurs that insult my child, I'd feel a tad different. But as it stands, this really feels like drama seeking behavior. There is no argument being made, it's just directing people towards Hexbear.
This is the kind of thing that Chapo got banned from Reddit over, the exact event that created Hexbear. If you don't like Hexbear, that's fine. They are generally drama starters, I don't support defederation but I understand why it's being talked about. But you can't call their users slurs, provide no context to what they said, and expect anybody in what is a safe space to be okay with it. It is literally the same thing that makes us discuss defederation with Hexbear, except they don't use slurs.
Asperger's is pretty ableist, albeit not popularly known as ableist. It was pretty much the term for the autism that Nazis saw as a superior subgroup of people, from the name of a Nazi doctor. While being autistic could get you killed by the Nazis, being diagnosed with Asperger's would have been a good thing. It's essentially saying that you have good autism and not bad autism.
Not saying anything bad about the meme because most people don't know the origin of the term and who doesn't love the ass burger thing. But I'm never gonna see the use of a Nazi doctor's name for this sort of thing as normal and will educate people at any opportunity. It would be like saying conjoined twins have Mengele syndrome. Yeah he started a bunch of research on conjoined twins, but he usually just brutally murdered them.
