I find it a bit disappointing when people, even on HN, argue on such topics like they are a method of opinion or life experience. If you read even a couple of books on evolution, even at a science popularization level (Richard Dawkins being a good example) it's pretty clear genders are far from identical. And that has been so since the first living things separated in genders. Everything, of course including behavior, is influenced by gender. This of course doesn't mean we should "let things be" and trust mother nature. Some evolved behaviors are better then others in modern society, but it's really surprising how few they are compared to the mass which still apply.
