That article reads like it was written by idiots. Aside from the fact that knowing self-defense is a good thing, most of the rest of their points are hogwash. Young Americans are not any more "submissive" than middle aged or older Americans. And teaching that violence is not the answer is NOT the problem. In fact, the falling rates of violent crime would prove just the opposite. Besides, at what point in recent history did we ever teach people that violence IS the answer??
I really love this bit: "Just as post 9-11, where people no longer submit and cooperate in their own murders on planes"... How many attempted murders on planes have there been since 9/11 that he thinks it would no longer happen??
