It seems weird to me that you’re on the meta for another instance complaining about a decision that doesn’t affect you.
There’s plenty of other comments here about other awful shit going on at lemmynsfw and I don’t feel like recapping that. From what I can see concerning the actual defederation, it is at worst the right choice for the wrong reasons.
The rest of the argument seems to be about the community’s intent. Including “child-like” in the sidebar of a porn community because it was copy/pasted from a dictionary definition may have been a ‘stumble’ but it was still negligent.
This is touching on the really inflexible damage system in DND. My games tend to have real hospitals/clinics for dealing with the wounded and sick in a way that can’t really be expressed with the DND hit point system. This is fine for my games though, usually this kind of medical care is addressed through roleplay and outside of combat. NPCs often get wounded in a way where a healing potion or spell will only stabilize and will not make whole.
