I understand, but unlike other "first world" countries, the US of A arose directly from armed revolution. England fought a civil war, executed their king, then shortly after went back to having a royal family that had a role in the government. So a return to status quo (sorta) (it was a constatutional monarchy) So our history plays a unique role, fueling passion. Up north, the Government could simply pass a law, and people had no tradition to resist such a law, Australia, England, etc all the same.
But here we have a tradition that an armed populace counters tyranny. So the passions are unigue as well.
