In many video games, especially MMOs, you can do the same kind of combat with a male or female avatar (in other words, from a gaming perspective, the differences are literally cosmetic). This is not a reflection of physical reality, although it is a nod to sexual equality in other areas. That being said, it is silly to pretend that before gunpowder came along to diminish the advantages that upper body strength confers in hand-to-hand combat, women could be equally effective in combat. ESR calls bullshit on a recent article that goes out of its way to imply that half of Viking warriors were actually female:
Better Identification of Viking Corpses Reveals: Half of the Warriors Were Female insists an article at tor.com. It’s complete bullshit.
What you find when you read the linked article is an obvious, though as it turns out a superficial problem. The linked research doesn’t say what the article claims. What it establishes is that a hair less than half of Viking migrants were female, which is no surprise to anyone who’s been paying attention. The leap from that to “half the warriors were female” is unjustified and quite large.
There’s a deeper problem the article is trying to ignore or gaslight out of existence: reality is, at least where pre-gunpowder weapons are involved, viciously sexist.
Supporting this, there is only very scant archeological evidence for female warriors (burials with weapons). There is almost no such evidence from Viking cultures, and what little we have is disputed; the Scythians and earlier Germanics from the Migration period have substantially more burials that might have been warrior women. Tellingly, they are almost always archers.
I’m excluding personal daggers for self-defense here and speaking of the battlefield contact weapons that go with the shieldmaidens of myth and legend. I also acknowledge that a very few exceptionally able women can fight on equal terms with men. My circle of friends contains several such exceptional women; alas, this tells us nothing about woman as a class but much about how I select my friends.
But it is a very few. And if a pre-industrial culture has chosen to train more than a tiny fraction of its women as shieldmaidens, it would have lost out to a culture that protected and used their reproductive capacity to birth more male warriors. Brynhilde may be a sexy idea, but she’s a bioenergetic gamble that is near certain to be a net waste.
Firearms changes all this, of course – some of the physiological differences that make them inferior with contact weapons are actual advantages at shooting (again I speak from experience, as I teach women to shoot). So much so that anyone who wants to suppress personal firearms is objectively anti-female and automatically oppressive of women.
