It's a white, bourgeois prejudice to find the seductive wiggling of a butt degrading. Even though I'm one of those supersmart white middle-class women, I don't have this jealousy. I'm strong enough as a woman to say that it's natural for a beautiful young girl walking into a room to capture the attention of all the men and women. That's an eternal human principle. It'snot white male hetero-sexism.
All people admire youth and beauty.
In the Greco-Roman tradition, youth and beauty are divine and worthy of worship. That's my theory. These museumgoers are staring at beautiful nude bodies for pleasure, and it's supposedly high art. The educated and rich get their kicks in museums. It's perfectly legitimate for them to want to look at beautiful female bodies.
