I agree, Abstract art is junk. It probably began when an artist was so upset because their painting was not going well that they began to throw the paint at the canvas. Then a moron came along and declared it was fabulous art.
I was in art school when I had to have carpal tunnel surgery on my right hand (pottery class did it).
While I was recovering from the surgery I signed up for an abstract class.
No problem........... I could do it with my left hand but it was still junk just like the other students paintings.
I got so disgusted with Painting Class that I HID OUT in the Pottery Studio! LOL!
Weaving and glass blowing were fun too.
