Your emoji game is strong comrade.
I also joined midwest.social because they claimed to be an explicitly leftist instance. It would be extremely disappointing if they defederate.
Honestly, federation with Hexbear has improved my Lemmy experience 1000%. I think it would be silly to defederate because a vocal minority of libs don't like their worldview to be challenged. You can individually block the instance if you don't appreciate the vibe.
As far as I can tell they embrace leftist unity which is something we could all use more of.
Am I doing it correctly? I tried to add them by manually changing my display name.
