Women have different interests: So what?
Face the simple fact that most women are simply less interested in STEM than in other things. In areas where women are interested, they have broken in very successfully.
Originally there was massive opposition when women wanted to get into Nursing and Medicine, but I believe that virtually all healthcare is female dominated these days. Similar battles were fought and lost over women entering the legal profession.
Women are just as good at technology when it interests them. I am aware of several successful women in tough jobs in heavy industry, but they are in the minority. The majority are more interested in other things, for instance I am not aware of of any female high voltage distribution engineers.
Women have made stunning technical contributions, for instance Beatrice "Tilly" Shilling produced "Miss Shilling's orifice" that kept the Spitfires flying in WW11.
One problem is that when men say "Women brighten up the workplace" women hear "The female function at this workplace is purely decorative", when what was meant was "Everybody dresses slightly neater and behaves better (even if it is just to have a chance of getting of with a intelligent and technically competent female)"
Of course if we are to have gender quotas for engineering, MPs etc then we should go all the way and lock up one female for every male we lock up.
