I believe there are innate, population level behavioral differences between the sexes which are, at least in part, driven by testosterone. There are also socially driven differences. It is impossible to separate out which are which as socialisation of babies according to their sex begins at the moment they are born.
That doesn’t mean that we should be bound by them, nor does it mean that you can tell who is a woman and who is a man, by looking at individual behaviour.
Ironically, I suspect that, if we look at behaviour patterns of people who claim a trans identity, they broadly adhere to those behaviour norms for their sex, despite their claim that they feel like the opposite sex.
Thus despite the increased aggression FtM transitioners demonstrate when on testosterone, they retain, on average, more empathy and understanding of women than their MtF counterparts.
And an outstanding number of MtF transitioners (especially those pushing themselves into prominent positions) are both aggressive and abusive in patterns that are commonly associated with other male abusers. Interesting to note that (in dogs at least) reducing testosterone in aggressive dogs can render them more aggressive. It’s not a straightforward equation as it is for FtMs when testosterone is added in.
I wish those early feminists pushing for women to be accepted as they are, but also as equal had prevailed. Instead, women have been pushed into competing in a world that was set up for men and it hasn’t worked well for many of us, especially once we had children.
Trying to find true equality/equity when we are physically different, bear children and started from a position of less power to influence, is going to be a very long battle that I suspect we will never achieve.
That said, I find it fascinating online when arguing with men. Their power is reduced when physicality and fear of them is removed. It certainly makes a lot of men very angry when they can’t control the conversation as they would in the boardroom, so to speak.
