For the most part, the animal kingdom displays many different variances in males & females. A lot of them act manly or feminine without a social construct like we have.<quoted text>
So you referenced a link which you disagree with to prove you were right? Okaaaay. Lol!
Anyway, I find gender in society to be a very interesting subject, especially since, particularly in the US, people get so insecure about it. What is "male" and what is "female" aside from biology is entirely subjective and cultural, no matter how much some people would like to think it was objectively defined the way they'd like. And even biology isn't entirely bipolar, given the presence of hermaphrodites and the fact that we can manipulate our bodies in ever more sophisticated ways. Which itself get's into argument about what is "natural", and the inherent assumptions about "natural" and morality.
There are many clear cut deference a between males & females, I don't know why you'd write it as "male" and "female".....
