Dan had an excellent recent video on comedy and performance and the distinction of healthy and unhealthy performance
(why didn't you also post this here? this is great!)
There is something I've been thinking that is related: I appreciate Schopenhauer's distaste for people's endless frustrating status games masquerading as reasoning. This also gets worse the more people are involved in a group discussion, there is even hard evidence from the great Kahneman that social discussion in groups leads to stupidity
The unfortunate thing about Schopenhauer is that he was a rather disgruntled and surly.
So as a strategy to handling that, yes speak with firm authenticity when it's relevant, but in a group social setting after people shift uncomfortably and then start discussing whatever nonsensical ideas are hip and trendy at the time, move into humor. That is, crack jokes regularly throughout the discussion, using wit to jiujitsu the phrases into the absurdity they are in jest. It communicates "I'm not treating this discussion seriously" or "this discussion is stupid, but don't worry I'm not suffering I can still enjoy myself", which is the only sensible empowered play at this point, socially.
In many ways comics already do this. George Carlin, Patrice O'Neil and Bill Burr are excellent examples of people who get laughs by simply pointing to the farcical absurdity of various contemporary trendy values and developments.
On performance: one thing I like about the hip hop cover set I am doing is that there is a lot of 90s hip hop that is funny but politically incorrect. I get a lot of enjoyment from belting, e.g. Ludacris' Area Codes and Mix a Lot's Baby Got Back.
