to expound:

the tankie instance or the nutballs on the fascist instance

here you reveal a conceptual misunderstanding, or rather, a part of the lemmy architecture which i disagree with. there shouldn’t be a concept of a “interest X instance” etc. it should be similar to a distributed storage model. so the concept of a community is not per-instance, it’s just an abstract thing that exists in conceptual space.

you already share water with them though. how is this any different? more seriously though, you already share internet infrastructure with them. the packets you just sent to make that comment could have been sandwiched between a “tankie” and a “fascist nutball”. that’s just the way it is man, there have always been crazy humans.
