Not sure where you see this Reddit community. For me, it is a million communities. Each sub is a cosmos of memes and rules and acceptable styles.
Discussion
All of the major subs have been subsumed in to the borg ideology. Niche subs get overrun, brigading is accepted against subs which admins don’t like, even subs that have decent communities get overrules by censorious central planners who tolerate only a tiny Overton window on the entire site.
