"It's extraordinary that you'd argue for violence as innate where drinking isn't."
"You argue that we must learn to drink"
Read this bit again, carefully.
First of all, drinking is not innate. Particular neuromuscular mechanisms that produce an efficient drink or suckle are indeed innate. Thirst is innate. Note here that dehydration is innate in that it is an inevitable feature of the system. Hopefully you will recognize why this is important to note in the present discussion.
stress arises from belief systems
I can only interpret this from the perspective of solipsism. I am not a solipsist, unfortunately, so I can by no means accept what you've written above.
"Please stop with this persistent and misleading comparison"
As I recall you are the one who introduced it?
"Your notion of 'physiological violence' is not anything, except the observation that I can organise my body in motion in a way dangerous to others. So what? That doesn't mean anything: I can also ride a horse, drive a car, sing, go swimming, cuddle strangers. I do none of these things, whatsoever the innateness of my capacity for them. "
Really, really strange. My point was precisely that "physiological violence" is inherent and latent to the functional and structural organization of the human body. It manifests from infancy. The ability, say, to ride a bike or swim a breaststroke is not in itself innate, though the physiological basis is related and is innate, but must be developed through maturation and coordinated through practice.
The simple point is that, like pretty much any other animal, humans have retained the instinct that allows them to attack or defend. Obviously, as I explicitly noted, social conditioning modifies the expression of violence by introducing things like context, foresight, propriety, and so on. Again: I am not saying that violence is inevitable or unchangeable or must be tolerated or anything like that. Come on...
And because I feel you may be unthinkingly privileging the social as somehow distinct from the physiological, it is crucial to note that the social is nothing but biological, and that the development of social competence follows a well-understood schedule, deviation from which is invariably a sign of neglect, abuse, or psychiatric/neurological disorder.
" the response to that which I will never ever agree is innate because a choice always is made between fight, flight and freezing. The experience of the state and then the choice to act upon it in a given way are separate."
Typical libertarian nonsense. In fact, to be internally consistent you would have to maintain that thirst, hunger, fatigue, and so on are also "choices" made by humans. This is the coherent, but extremely-primitive egoistic conception of reality as depicted in the Iliad:
Achilleus has made savage the proud-hearted spirit within his body (IX: 792-793)
Finally, the response and the sensation are typically inextricable precisely because they both are produced from the same cause. I've already mentioned that.
