I’ve been reading that, by nature of our very existence at this point in time, most everyone has been endowed with the genetic propensity to behave violently. Given the necessary provocation, or not, our ancestral drive for survival has instilled the will and desire toward physical aggression in the interests of protecting kith and kin on the positive side and for some of us who may be leaning toward the psychopathic, rape and kill for personal gain. Violence may be the prevailing characteristic of humankind given our histories of Wild West lawlessness, clannish feuds and nearly constant warring.
Passivity is, I guess, a logical reaction against having to deal with any sort of revenge perpetrated upon us by survivors of aggressive behavior on our part, who, then, would have to be back-watching for retributive response from us, which would likely create a stand-off and perhaps perpetual distrust, which would place everyone in a fairly constant state of tension.
So, I’m sticking with passivity; I’m anxious enough as it is.
