If adult swim is known for anything it’s canceling their hit tv shows. You know how early Hollywood had a rural purge, if Rick and morty is canned I’m going to call the period from when they canceled metalocylipse to Rick and morty the dudebro purge.
I'd refute that it espouses much 'lib shit', if at all. The worldviews people seem to hate about it are nihilism and 'one guy can do everything'ism, but I've never seen the show actually depict those as particularly overly good things.
