As for gender, well, I'd better not go into that topic. I'll just point out that people have been writing about these matters since the dawn of history, and it's very naive (though sadly common nowadays) to believe that only our modern age has managed to achieve accurate insight and non-evil attitudes about them.

Dawn of history? Now I'm imagining uncovering writing on the wall of caves: "Why women make better hunters" and expressing indignation at under-representation of females in cave paintings of battles.
