In a perfect world, maybe. With some really good teachers, certainly. In the world we live in, though, the purpose of school is indoctrination: to turn kids into good obedient little citizens consumers. In particular, with regards to teaching history, to turn them into good obedient patriotic unthinking cannon fodder laborers.
Please calm down. This isn't 1984. Or Stalin's Putin's Russia.
It takes a LOT of work to indoctrinate people. Teacher's simply don't have the time, or control over all the different channels of information. Ask Hurlshot.
Anyway, point is still that the gun is what the devs make of it. What they choose to turn it into in terms of fights and powers. The gun itself is no more than a tool.
