Yes and no. They are federated with many communities, but the larger anti-Marxist instances like Lemmy.world are not federated. That's by design, Hexbear wishes to protect their marginalized members such as their trans, queer, gender-nonconforming, and EM/POC communities.
None of it is visible to me anymore, but I'd welcome you to view the admin defederation announcements, many of which included rationale and examples of that content.
So, nothing? Are you just a right-winger anti-Marxist that saw a picture of a pig with poop on its balls and cried for defederation? What was that about free speech, again?
They defederated with .ca and .world because of all the racism, transphobia and general right wing culture in those instances and that's basically all of the parent comments in here
Idk about .ca but .world defederated preemptively from .hexbear because their admins are selfaware wolves who knew hex would point out their rightwigness.
