Your logic is completely broken. Yes, war brings out the worst in human nature. . .
As much as I might wish to take credit for a colorful theory which is spectacular wrong, it's in fact not my theory!
It's the whole Sigmund Freud idea that sex is shot through even the most seemingly non-sex activities. And even though I'm generally skeptical of Freud, I don't want to make him some reverse authority, where if he says something, the opposite is true.
Or . . . the idea that bonobo chimps are both more sexual and less warlike than regular chimps.

Or, Nike had a shoe factory in Indonesia and most of the workers are women. The PR guy almost said because they're more submissive. A little like the chief executives are assembling a harem? A male boss who's a mean guy could use the situation for sexual harassment. A more regular male boss might just enjoy being surrounded by women and being looked up to, at times both literally and figuratively, maybe without fully realizing all the social and sexual dynamics involved.
