Modern “art” is very often offensive, but usually that is seen as a good thing. It’s “irreverent”, it “challenges norms”. I suppose the problem is that this particular hack challenges the wrong norms?
I don't see him challenging the norms, so I'm gonna guess "no". It seems to be that his art is a dime a dozen sort of low quality crap. Crap is in itself unsurprising -- most of everything is, see Sturgeon's Law -- but what's surprising is the amount paid for such low quality, low effort crap.
Not really. The author points out some misogyny in the work. That's a pretty common analysis point and is certainly not sufficient to "cancel" an artist (de Kooning is extremely famous and his pieces sell for gazillions despite some criticism here). That is different than "challenging PC norms".
No sign of norms being challenged here.
