I define "Social" as everything up to the point where someone decides to injure the other person which in-turn equates to violence... wether it be a knife to the spleen or a bat to the head or breaking an elbow joint. None of these things are acceptable on a social scale. A football game with crowbars is no longer social or sport. An mma competition where "fighters" break joints and inflict trauma on the other competitior instead of submitting them or inflicting pain is clearly a violent situation which is devoid of social standards and rules of conduct.
Make sense??
Pardon me, but by this definition, anything short of a berserker attack (suicide bombing, juramentado, etc.) has a social component. This is equally true even in a criminal assault. When a mugger pulls a knife and demands your money, there is an implied social contract, ie you submit and hand over your wallet and he will let you live. When a loan shark's thugs break your knee for not paying up, you can submit, and live (as a cripple) or fight and take your chances taking on the mob. I don't get in fights. But once, a long time ago I did. Before it went to the ground, I was losing, but I had a clear shot at seriously messing the guy up. He got me in a "red-neck rasselin" style headlock. I slammed him back into a car and had a real good shot at his jewels. I also had a large screwdriver in my back pocket and could have stuck him in the gut, pumping it like a sewing machine. I chose not to... and, guess what? We ended up on the asphalt, grappling. Even in an all-out fight, there are social consequenses to escalating things to that level. Even war has some rules. You don't kill and torture peoples kids and families. Normally.
So I guess my confusion is over this "social" distinction. I don't see it quite as clear cut as you. ...more of a sliding scale, depending on the situation. And, in the world I live in, I wish I as better at grappling.
