A careful read of the meme shows were talking about edgy, borderline right wing shit postings.

What? Maybe some people join communities for fun and togetherness. Not amateur hour jew jokes or whatever.

Very enlightening meme you have added to the conversation.

The shit posters drive a wedge in a community and the people who don’t like the “innocent” jokes leave. This makes fertile ground for ideological take over. Rinse and repeat in Fandoms, subreddits, message boards, etc.
