Insofar as a common and significant link ‘twixt the intimacy of driving a knife into another person, to the one, and coital penetration, to the other, is testosterone, the act of shooting the place up starts to seem very nearly masturbatory.
The psychoanalysisα of that proposition is probably as fascinating as it is grim. At some point it seems to denigrate the American shooting crisis while exploiting the very notion of rape culture, and it is easy enough to call any mass-murderer a pathetic wanker. Yet the analogy persists, and it is easy enough to regret, before it is written or uttered, any phrase about shooting his load in public.
Killing is intimate. Killing is also distal.
He can tell her he loves her; she can believe him; it can be true; and the link between this passion he shares and the violence he might commit against another is testosterone.
α The temptation to dismiss, out of hand, expected pop-culture strains of evolutionary psychology according to their obvious weakness presuming coital penetration as inherent to the existential justification of sexual differentiation, would be erroneous in at least one context, as the apparent fault becomes at least symbolically relevant; to the other, invoking semiotic values might be an overstatement. But where the pop strains of evopsych would discuss men evolving to penetrate women, Y previously evolved, and, indeed, continues to this day to adapt and select and evolve, not as delivery unto X, but as environmental distribution of gamete for X. Where human males may have specialized for gamete delivery, this is merely specialization of gamete distribution. And while it is true enough that word games are easy, and phagogenesis could, artistically, at least, be argued an intimate precursor to general environmental gamete distribution, the greater danger is the potential for evopsych to finally recognize the argument that masculine raison d’être really is to be a wanker.
