And yes... "an armed playground is a polite playground" since you insist on trying to obfuscate the issue with absurd arguments. At least there wouldn't be any Klebold/Harris mass murders that would make it past the first classroom without being plugged by their classmates.
Naturally I am not discussing rifle ranges in schools. At one time they were even allowed in Chicago schools. Kids brought deer rifles in season to schools when I was a kid but they were not allowed in schools because of the "fascists" tyrants running them.
Just as I said proposing that children should be allowed to bring guns to the classroom is the best way to endanger Second amendment rights. There is not a thing absurd about the example though there is about your response.
