Yes, I think us Brits defused many of our internal tensions as a mult-cultural AND classist society in the 70s and 80s with the transition from vaudeville racism to new-wave "alternative comedy". It didn't change the status-quo but it did move the dial toward more progressive ideas.
I do think HN is an odd place in it's intolerance of humour, and I don't see that "high bar" because TBH it's the lowborw geeky "knob-gags" that make the grade here in my observation. I think it's actually the old struggle of poets and philosophers (see Republic 2, 3, 5 [0]) is at play. HN adapts to filtering what it can't process. It's a bit like that AI brain in Blake's Seven that Villa causes to explode by feeding it riddles. I'm noticing even this "meta" talk about humour is being downvoted (and I hope those doing so are getting a good ironic laugh from that) :)
