We live in a society where people who engage in sociopathic, violent behavior tend to have the full force of the law dropped on them. That's an example of co-operation: The thug down the road might be able to beat me over the head and steal my wife, but can he resist the SWAT team when it comes to arrest and/or kill him?
That only by virtue of having bigger guns you can force people to cooperate with you? And your label of sociopaths may make you feel superior to them, but it doesn't fool me. They don't agree with your version of society? You don't agree with theirs. Why are they the sociopaths and not you?
As I said, it doesn't matter whether you call them your homeys or your police department, having stronger thugs on your side is the way you survive. If the police were on their side you WOULD be the sociopath by definition.
The fullest evidence that Darwin is against our social structure is that all similar structures in the animal kingdom are also maintained by force. The strong survive and the strong should survive. Only when the girlie-men of western civilization understand this will we be able to guarantee our survival against the barbaric forces arrayed against us. But I doubt we will. Greater civilizations than ours have fallen into that same feel good trap.
Shalom.
