It has been a project of the American Left to destroy Western civilization, or at least its history. It seems like a fool's errand to me, but also evil in a way.
It might work in spineless academia, but not in real life. Stop by to see a show at the Metropolitan Museum in NYC sometime. There will be a line of thousands from all over the world waiting to get in. Every language, nationality, color, etc. Universally known as best museum in the world if not best in every single area.
People know what is amazing to look at, despite academic fads.
My high school Art History course was mind-expanding, cave art through Egyptian and Assyrian up to the Renaissance (yes, we had to learn the math of the Parthenon's steps and of the columns), and the required semester of Art History Intro in college almost equally-so. We learned a bit about Asian and African art too because of their influences on Western art and design.
Yale is getting rid of it. It's "too white."
Pieta was carved by Michelangelo at age 23. That is just not normal. What have I done lately? What have those students and academics done lately? Those smartypants are not Michelangelo.
