It's one thing to describe the experiences of soldiers returning from Vietnam, because that is valuable information. It's another to interpret it and make conclusions when there are 50 other valid explanations.
"People/men like war/aggression/risk" is honestly not a new concept, and it's seems pretty correct on the surface, especially when you cut out the whole part of your comrade slowly dying due to a stray shell. This is the glorification of war that books like Catch-22 and Slaughterhouse Five were written against.
Most incorrect claims are dangerous, and the reasons are not always all enumerable since you often can't see the problem when you think a false thing is true. I.e., if you already think women are hysterical, treating them as hysterical doesn't seem like an issue because, well, they're hysterical.
I would say that first that I never said anything about gender-specific, or if i did it was a mistake.. My point is that every human (men or women) has a potential of violence that can be unleashed in many situations. This potential is the kind of thing that look "unnatural" "scary" or "bad" when you see it and don't feel it but feel naturalyou experience it.
Granted there's not many data / source in my answer. My point is just that I feel a bit weird when I see a lot of articles like this who talk about violence being an "unnatural" tendency of the humans when I think it is a very natural tendency (which we constantly try to make disappear in our peaceful societies, which is why it might look unnatural nowadays.).
