I got into my fair share of trouble when I was a kid; both starting fights without any real provocation and being the recipient of aggression without any real provocation. Much of the time it was caused by an unnecessary escalation of previously fun 'play' violence (towel fights in the locker room was a biggie).
I can only think of two fights that were prompted by some form of emotional argument or dispute: In middle school I fought a bully at my bus-stop, and a year or two later a kid I had been bullying in boy scouts nearly broke my nose.
I think you're unnecessarily narrowing the definition of "emotional manipulation".
I also do not know what "real provocation" is and how it differs from "not-real provocation".
"Real provocation" in my above comment would be the sort of "emotional manipulation" that you are talking about.
Conveniently, this makes it impossible to map out any potential emotional manipulation. It's like saying that World War I happened with no real provocation; it was just these random nations snapping towels at each other and somebody got hit in the balls, boo hoo.
Tell me who these hypothetical people are, who flip a switch and kick their neighbor's ass for no reason. Tell me how many months older they are. What competitions did they win recently? What's their relationship to the teachers? How long have they known each other? Why are some of them friends, and others merely classmates? What do they look like, to each other? What are their parents' relationships? What clubs did they join? And so on and so on.
The idea that women are mostly feelers and men are mostly doers writes off both men and women as useless stereotypes.
