That's about how I feel about the whole "Human Nature" meme. While there may be traits inherent to us humans, at the same the "But human nature!" argument is more often used by assholes to justify assholish policies that run over the rights and lives of other people.

Plus, the idea that humans are inherently violent brutes, really doesn't hold up. Everyone goes on and on about how if there's a disaster, we'll have all these panics and riots, but with every natural disaster, what happens is that the vast majority of people do what they can to look after each other and help each other out. There are a few bad seeds who do some rioting, but they are few and far between. Most research shows that humans are generally wired for altruism; we are wired to be kind to each other and help each other out.

Agriculture on a massive scale didn't really take off until ten thousand years ago, yet Homo sapiens have been around for about fifty thousand years. If we were inherently violent and unstable and needed a massive State to make us be good and not hurt each other, how did we managed to survive for forty thousand years without it? Surely we would have wiped ourselves out ten times over.
