It isn’t merely a few who do it now and then. It has been going on since the dawn of Man by a very large portion of the societies in just about every society. The intelectuals merely do it in an intellectual way while others are doing the exact same thing, but in a less intellectual way. And that turns out to be the majority of people, mothers, father, children, scientists, priests, politicians, carpenters … everyone is trying to alter the world to fit their preferences in at least some small, very often stupid way.
Anyway, I think this takes us away from the answer to your question- yes, there is a good reason for their to be a difference between the sexes- some intellectual believing that difference is key to their utopian or political vision. Likewise there is an identicle reason to want to annhiliate that difference- some other intellectual believes it stands in their way. Ultimately, I don’t think intellectuals deciding whether or not we should have things like genders based on how it impacts their personal visions for everybody else’s future is healthy. Gender differences are quite clearly real and there and people act according to them in fairly typical and universal ways when left alone to do so.
If this was 100 years ago, I would probably go along with that. But the truth is that social manipulation has gotten to the extreme point wherein people are already acting in very insidious ways to reform nature even to the point of dispensing with gender entirely (by several ways). It isn’t like I am inspiring a new social movement here.
And then since such things are going on anyway, why not get the question out in the open and resolve the question of actual need rather than ignore it and leave it up to the most insidious thinkers on the planet.
The need of the difference between males and females is to prevent the extinction of homo sapiens.
But all that is going to happen is that “homo-sapian” is going to be gradually redefined until it has actually been extinct for a very long time before anyone notices; “mutants”, cyborgs, Rev2, “new and improved”,…
