Directness necessitates subtlety and nuance. You are making big claims about "good art" and what it entails, but I don't see how something must be satire or indirect to accomplish this. I don't even think satire is inherently bad, but I think it's pretty clear what purpose it serves in the modern world since it's massive proliferation in the 20th century.
Also, people don't misunderstand art because they are "dumb."
Why are you assuming that non-satirical art is inferior? Wouldnt you prefer art tackle issues directly instead of abstracting them into meaninglessness?
Things have gotten really bad since Israel escalated their war against Iran in terms of shitty doomposting
