I get you. I love art, but my love starts abetting somewhat after the Impressionistic period. But because art is so subjective, I always think of the Supreme Court ruling on pornography. “I may not be able to define what pornography is, but I know it when I see it.” So it is with me & definition of modern art.
Plus I’ve heard enough people say, “I may not know art, but I know what I like.” I made it a point to educate myself on art, modern & otherwise, just so I can say, “I know art, & I know what I like.”
