I think you typed out a snarky reply before really thinking about it.
If you consider cops girly men, so be it.
If you consider military folks who have had to kill people having trouble with it and being grily men, then so be it.
I base my response on actual conversations with regular people who have had to kill someone in self defense and watch them die (even if they are criminals). I base it on the discussion psychiatrists have had regarding the kind of severe, immediate assault on your mind when you are going through being in a stressful situation where YOUR life is at risk, and to defend it you wind up taking another person’s life. And these are people that know they had no choice, feel they did the right thing, and it still is a big stressor for them.
Plus going through the whole being arrested and treated like a suspect rather than a victim of violence, by the police, then waiting for it to be ruled a justifiable shooting, and then waiting to see if the crook’s survivors file a civil lawsuit against you, going through lengthy and stressful legal processes.
It is tremendously stressful. From your reaction I can tell you have never had to go through it.
Sorry. I didn't realize you were "special".
