Do men and women have genetic equal opportunity? No, but which sex is more privileged biologically, including psychologicaly?
Do men and women have cultural equal opportunity? They are so obviously different, but how much of it comes from the biological differences? Afterall, things developed naturally enough from the beginning under the singular influence of nature.

I guess my point is that it doesn't do any good trying to elevate one above the other. It's obvious to say that one can't exist without the other, but that's not the point...

Food for thought: the civilization as far as men goes in the USA is growing weaker. Never before has there been such a feminized society. Not ever. USA still leads the world in many ways.
What's good or bad about it? As my first argument suggests, natural law speaks for itself. Maybe women are getting stronger, but if anything in a species changes at all, without evolution present, it's probably a cultural thing.
