I found r/sigmarxism back when I was into warhammer 40k because somebody told someone to go back to r/sigmarxism because they posted a meme about how the mechanicus are basically just all non-binary.

It's pretty amazing how they've managed to basically purge the more noticeable elements of fascism from the community - the fascists are still there but they're on the back foot now; if anyone even mentions the name 'Arch [redacted for legal reasons]' they'll get immediately downvoted to hell (and on r/40klore mentioning him is actually a bannable offence now).
