What do you do to remain violent in modernity?

It has dawned on me that it is likely a relatively new phenomenon that an able bodied man in the prime of his life does not use violence for basic sustenance in food and shelter, doesn't use violence to promote himself in sexual selection, celebrate in violence when the conqueror and has evolved away from teaching the ways of severe violence to his children whether it be against animals or other men.

At top of mind (from reading the aforementioned book on Comanches), just as far back as 150 years ago, if you are a native Texan, your grandfather's father was likely savagely killing other men, impaling, torturing and likely enjoying it a little bit too. It was either that or his kids were being stolen, his wife was being gang-raped and he was being killed and tortured with his testicles in his mouth or burned to death on a skewer. Respectable men and not just trained militia and military -- preachers, lawyers, sheriffs, teachers, land owning gentry-- were hardened in the ways of killing fellow man.

Men that could be fit, and later were in Andrew Jackson's case who lived the rest of his life with lead in his body from a duel he survived, to be a President of the United States used violence as an acceptable tool in their problem solving kit of life.

Sixty years ago we had a massive World War that sped boys through the threshold to manhood in warp speed and provided a built in rite of passage. These boys and later men were in general shown to be wise, judicious, smart, strong, responsible and reasonable people. The greatest Americans to ever live, as we so dub them with the "Greatest Generation" moniker, was nurtured by violence. 

If we treat that last statement as one devoid of irony then it must be held as evidence, the exhibit A (or B or C), that violence as a psychological or character trait is endemic to the success, "goodness", and glory of the American people.

And yet, today and in the recent past, we have attempted to "evolve" away from it. Outside of the USMC on the front line or whatever and the dispassionate poor mired in poverty (a modern day "Noble Savage" in the J.F.Cooper archetype), there is a conspicuous lack of violence both in our culture and everyday lives as we hold keeping peace as the higher and more noble ideal in much the same way we view humility as being superior to pride.

The question then is: Is the lack of violence a good thing? On an intuitive level we would knee-jerk a response "Yes", but I think the more important question is: What are the social costs?

To you personally: What do you do to keep refined your sense and ability to impart violence in a modern world?

Do you watch or participate in physical sports like football, boxing and MMA type training?

Do you get drunk and high and shoot semi-automatic guns with your buffoon friends?

Do you shoulder check people at baseball games or otherwise get in bar fights?

Do you get online and call people fagets and virtually talk shit/e-fight?

I, for one, need to focus on being a better American by way of being a better man, I think. Excuse me while I have a glass:
