It's mammalian nature. Men are territorial, and women are territory. I know that's not the "popular" view or anything that any one wants to hear in this enlightened age of total denial. But the fact is that over 2 million years of evolution has made that the law of jungle. Most of our societal ills come from us fighting our nature instead of channeling it. The objectified art is just a reflection of what we want, and we want it because there is no healthy normal direction for us to channel our desires. Some how we got locked into artificial behavior like monogamy. Add in the ever changing aesthetic of society and our new age of technological separation ... you're just asking for problems. You can't tame an animal that you're pretending doesn't exist.
