Yeah, I got that context now, which I also accounted for with the "usually" qualifier. I still think it builds an attitude that is toxic to outsiders and can potentially push someone into a right-wing position. I have witnessed first hand how someone fell down a fascist rabbit hole via online places touting language superiority.

bro just skipped the "usually" part and made a rant against things being judged politically.

I think the "everything has to be written in German" part of ich_iel is also establishing a rather nationalist online culture through linguistic homogeny and illegibility to outsiders. So, yeah, you may not want to recognize the impact your words may have, but it's clear to many others.
