> As far as I can tell from on the usage of based I've seen, it means cringe/unpleasant/racist (depending on context).

Again, you need to separate your feelings about the things being described as “based” with the meaning intended by the people using the word. If I hate hippies and think anything they call “groovy” is really ugly and uncool, that doesn’t mean I get to just declare that “groovy means ugly and uncool”. That’s what you’re doing.
