Most people in our society don’t understand violence. We’re taught to feel like it’s a “bad” thing to even think or talk about, and what this leads to is that most of us never learn much anything about it. That’s not a good thing.
Those who are furthest removed from violence in their daily lives are the most vulnerable to it when they suddenly run into it on a dark street precisely because they don’t understand it and therefore act stupidly and end up “asking for it” and getting killed. Most churchgoing taxpayers just have no idea how violent people think. Women, especially. If there are any women you give a shit about, you will make sure they know about this stuff. They probably have no clue about any of this, and it may one day save their lives.
Although men generally grow up better acquainted with violence, the scuffles of the playground still leave a person totally unprepared for violence on the streets.
The writer's advice is basically, give the mugger your wallet and get on with your day. Your wallet isn't worth losing your teeth, or your life.
