It seems to me that you’ve confused a type of art with ART… a common problem where people only have enough brain cells to hold one definition at a time.

I have successful friends that create traditional art, ones that create post-modern art, ones that create pop art and ones that create dada/OpArt etc. To hold that ANY single artist or style of ART somehow changed the entire Art World sounds, to me, like nonsense. You’re comparisons are poor, your statements, while full of accusation seem quite low on proof/details or even a well structured argument.

Go take a class on Art. Who knows, you may actually learn something if you allow data to enter the mind, rather than just clinging to whatever opinion might spring fully formed from your brow, like Athena popping out of Zeus.

Artists like the Dadaists and Pop Artists laid a foundation which tore down the Fourth Wall… it took art from a one way sort of communication (The Artist ideas, aimed directly at your head) and turned it into something much more interactive. If you don’t get that… maybe you should read more and write less.
