The Dada movement was an effort to sever humanity from it's artistic history by elevating the irreverent, the lazy, and the ugly.

By removing from art talent, style, and, simply speaking, "art", there is a vacuum left ripe to be filled. Today we see that is used for that fill: propaganda and communist rhetoric. Bullshit ideas wrapped in "art is subjective, bro." The same that happened in China in the 60s.
