I know that I've said this elsewhere (probably multiple times) but many women don't realise just how much of an advantage male biology has over female. In the bad old days where everyone had fifteen siblings and every scrap of food was fought over, and they watched their fathers smack around their mothers on the nights he came home drunk from the bar, it was pretty obvious to everyone.
I've seen trained female fighters take down males, but they had to be fast and they had to be precise, because ultimately, all the males needed to do was land a single blow to that delicate female jaw, or even just rush and pin the female fighter with their heavier frame.
There's video of a troon boxer losing to a woman, and if you watch it, it's clear that the woman won because of technique and speed, and because the troon clearly expected an easy match and didn't bother preparing a defence. The woman made every single blow count because she was thoroughly aware that if the troon managed to land a single heavy blow, that was the beginning of the very brutal end.
Action movies and shows with Buffy or Charlie's Angels are fun, but having them block blows from muscle bound thugs three times their size, and not having their skinny forearms snapped like twigs is unrealistic, to say the least.
I guess every girl needs an arsehole big brother to wrestle with, otherwise she ends up with weird ideas about biology.
