Erm. We follow archaic laws to this day that were beneficial to pirates stealing, raping, pillaging and genociding across the world to create and uphold an empire.Some Americans have such a weird relationship to their constitution. It's almost like it's a religious text, and they think they are the only country to have one. We have a constituion as well, but if it consistently produced horrific results in the present day I would be all for changing it. They are desperate to be controlled by what a bunch of slave owners wrote down a couple of hundred years ago. It's bizarre.
I'm sure other nations look out our courts and the wig wearing as equally bizarre.
If guns were hard-coded into our constitution as it is America's we'd be as devout to it as they are to theirs.
