Thanks for providing me context. If it helps to display the depth of my ignorance about comedy (thus trying to get more context to the claim) I don't know who any of those names are.
Sorry, it's a very parochially British viewpoint. Perhaps where you
are there's also the same undercurrent, just not visible in the
mainstream. You may have to dig a little.
Cultural malaise often hides beneath the surface. One of the most
frightening accounts of this, on a more international stage, is what
Slavoj Zizek had to say on it; He said that in the former Yugoslavia,
humour kept ethnic tensions at bay. The civil war was foreshadowed by
a creeping political correctness and people "not finding things funny
anymore".
