Let me expand on this old soldier's excellent model of the sheep, wolves, and sheepdogs. We know that the sheep live in denial, that is what makes them sheep. They do not want to believe that there is evil in the world. They can accept the fact that fires can happen, which is why they want fire extinguishers, fire sprinklers, fire alarms and fire exits throughout their kids' schools.But many of them are outraged at the idea of putting an armed police officer in their kid's school. Our children are thousands of times more likely to be killed or seriously injured by school violence than fire, but the sheep's only response to the possibility of violence is denial. The idea of someone coming to kill or harm their child is just too hard, and so they chose the path of denial.
It's not too long of a read, so check it out.
