I am a gender critical feminist too, and I see children as individuals. If you go in looking for confirmation of girl/boy differences you are likely to find them. I could be wrong, gender traditionalists could be wrong. Who knows for sure..
I was one of three girls, and we were all brought up to do all sorts of 'boy' things including using an axe to chop wood from about age 10, and helping dad change the oil in the car, etc. Somebody had to do it. There were no boys so we girls put on our anoraks and hats we had knitted in handwork class and out we went. We also learned to cook and were encouraged to learn knitting and sewing and domestic arts in general though a lot of that was water off a duck's back for me, to my regret, because I later had to learn on the fly.
I have four DDs, each one of them her own woman, and very different growing up. DS was different too, but I can't ascribe the difference to him being a boy. One of the main differences I noticed was that DS used to like to get down to wheel level to look at how the wheels turned on his truck, while the DDs used to pile dolls and stuffed animals into the truck and incorporate it into a narrative. But DS could also play pretend games, and he had a huge invented story about the building of our house, complete with a name for the man who built it.
The teen years were easy for some and rocky for others. In general, DS was terrific in situations that required harnessing nervous energy - driving test, exams in general, and putting his ears back and studying. The girls were better at steady slogging, but DDs1 and 2 were also great revisers and took exams in their stride. DD3 was a bit more nervous, and DD4 dealt with exams by just ignoring them. Each one different. All of DS's friends are different people too, and their dads have different personalities, deal with things differently. I really don't think we can generalise.
