How did we do it 100 years ago? Just do that. The way we’re raising kids these days isn’t working right.
100 years ago the kids “toy gun” was a percussion revolver with just the caps...
Well, my generation, back in the late 1930s and early 1940s, played Cowboys and Indians, chasing each other around and shooting cap guns at each other. Once the war started in 1941, it was now longer Cowboys and Indians, it was the Army/Marines versus Japs or Nazis.
I don't think our playing ruined us. We were the generation that fought well in Korea and Vietnam.
I don't think it would hurt to raise another generation the same way.
