Subreddit mocks cultural gatekeepers

r/gatekeeping is a subreddit dedicated to collecting and mocking examples of gatekeeping in popular culture and fandom: the act of telling you you aren't allowed to like something unless you meet arbitrary or esoteric requirements. Reading some of them makes me think that the "gatekeeping urge" is so fundamentally primal and dumb that gatekeeping call-outs could easily be generated by a computer program to a Poe-complete level.
