That's probably a lot more true for when dodgeball was allowed, kids picked their own teams, and called their own fouls. Things aren't like that anymore, and the number of people who have been sheltered (including by their own choice) from any kind of confrontational/adversarial activity is a lot higher and growing. There have always been people who do not react well to those things.

Those are the people who need different handling to guide them to a place when they will gain benefit from force-on-force scenarios. Sure, it's not going to kill anyone, but I can find a number of people that if we put them through an intense scenario one time, they will never, ever do it (or go shooting) again and will probably make them even less able to effectively defend themselves.

Again, being "ready" for this kind of thing has little (if anything) to do with weapon skills. You can't force people through their personal emotional and psychological adjustment. You can guide and accomodate and suggest and most will probably get to where they need to be eventually. Identifying them isn't tough. When those people self-identify, it's called a "clue."
