I realize as a Californian we may not count as "American" in this particular zeitgeist stereotype. But FWIW we have a firework ban in Nevada County that is widely respected. There are very few violations and the law is actively enforced.

The difference is we are in a no-joke dangerous fire situation and everyone recognizes it. Most people know better than to set off incendiary explosives in a forest. Anyone who shot off illegal fireworks would immediately be shamed and censured by their neighbors. I guess it's a form of commune-ism.
