A good measure of cultural fragmentation is how far on average a joke has to travel out of context for it to cause offense When jokes hit a mean free path of one degree on social graph you’ve hit anarchy
Dude you’re the one claiming we’re at zero mean free path for jokes which is clearly not the case because I can *see* jokes traveling farther all the time. Pro comedy is irrelevant here. Stage humor does not determine cultural fragmentation levels.
