Yes, men and women are different. What feminism used to press for was that they should be allowed to take on the careers, occupations and lifestyles that they wanted, without being told by the establishment that they would not be permitted.
By establishment, I mean two things. First the legal, political, educational, church and business frameworks which barred women from getting degrees or apprenticeships for the "male" occupations, or becoming lawyers, doctors, and priests. They even had no control over their own money, all of it going under their husband's control as soon as they married, or their children - a husband could make decisions about their education and welfare without consulting his wife.
Then the social framework, which closed its eyes to men with mistresses but labelled those mistresses as "fallen women" and ostracised them (read the novel "The crimson petal and the white" by Micael Faber) and condemned "unladylike" leisure pursuits like cycling, which would render them unfit for bearing children, and probably excite their baser passions too (read the novel "While the world is still asleep" by Petra Durst-Benning)
Also the attitude of the "man-in-the-street", who knew what he wanted in a wife - one who had his meal on the table when he got home from work, didn't argue when he spent the evening in the pub or the club, was compliant when he came home and felt like a spot of nookie. Then there was the attitude of the slightly more well-off that it was an insult to him if his wife wanted to have a career, "Don't I make enough money for you?!"
Women are now admitted to the universities and the professions, they are equal financially and in law. They now (only recently) have equality in the church, that philanthropic institution whose founder stated that there was no differentiation between men nor women under God. They can do in law whatever job they choose to, they make family decisions, they are not to be discriminated against.
What takes a lot longer than the legalities is the residue of hundreds (thousands?) of years of social acceptance that might is right and leads, and the weaker follow. It was the norm that the "stronger" sex which made war and trained with weapons and beat the rebellion out of anyone who argued with them has the monopoly of certain behaviour and preferences, and the "weaker" sex, which bore and nursed the babies and made the meals and clothes had the monopoly of other traits.
The media and the retail trade, with their frilly pink for girls and their macho gear for boys are still continuing the stereotyping. Most children grow out of it, but it still lingers - how many (female) GNers were horrified at the tales on here of rats and spiders?
