This is a bit of a hole that feminists understndably dug.
Women were excluded from a multitude of things due to our supposed inferiority. We were not allowed to vote, own property. We were property. Children belonged to their fathers. We were shut out of systems of power, commerce. We were not allowed to compere in lots of sports stuff like FA essentially banning women's football when it was a really popular sport with crowds coming along, boston marathon, of course parliament, you know all that stuff.
So our argument has to be, we can do what men can do. Our brains are not inferior. We can think.We do so maths, science, we are rational, we should be allowed to vote, to be in business, to be in parliament & etc.
Of course for that - for all of that - it never really occured that anyone would say OHO so you say there are literally no differences between men and women >> the differences being so self evident that no-one really mentioned them, they were not on the table. So sports were separated by sex.We were now allowed to compete, the idea of playing the men was never on the table as it was self evident it wouldn't work. For example.
The "OHO so you say women and men are the same" started coming out from smug men and MRAs however many years back usually citing the different numbers of sets at wimbledon and saying women should play rugby against men and HA see how you like equality now.
So the message that was needed >> we can do anything men can do (but actually we never meant that stuff > and no-one took it to mean that stuff because it was obvious) to get the RIGHTS that we needed to be at least theoretically equal in society was right for the time.
Now we need a different message because when feminsts essentially said "we can do anything men can do, we should be treated equally" we didn't ever mean that men aren't much more violent than women which they undoubtedly are (nature / nurture) nor did we want things like that prick thingy davis (?) the MRA on the equalities committee demands, such as more women being sent to prison so the numbers match the men, in the name of "equality".
This also applies with a return to valuing things like pregnancy / maternity ect - previously the only way to get our stuff was to pretend that these had no impact that they were trivial that they would not "hold us up" in a man's world, otherwise we would still be locked out. Few decades now these areas of specifically women's experience and the rights we need around them have been flagged more BUT it suits commence capitalism to pretend these things should not prevent women working for more than 2 seconds etc etc.
It's all a bit complicated.
The fact that women are as capable of thinking and working and driving and voting and stuff as men
Does not mean that we are exactly the same as them
The self evident truths that no-one bothered mentioning are now being challenged (women and men should play sport agianst each other. sex segregated spaces are sexist to women and oppress us. women are just as violent as men and commit just as many sex offences) and so we need ot challenge back.
Luckily we have facts on our side so that is great.
I can see that men are a bit pissed off that we have invaded and "taken" all their stuff - while we still demand some things just for us. But, they're missing the historical context, the fact of systemic oppression of women and girls for centuries, the facts of our biology, and the fact that men present a genuine danger to pretty much everyone, but expeically to those smaller / weaker / more vulnerable than them and most men are heterosexual so girls and women are more at risk.
