A document that isn’t in the bible, so it bears careful scrutiny no matter how long it has been in hallowed history.
America might have talked God-talk but its walk was at best a mix that included a lot of world-walk. God has practically said by now “I bet you now wish you only had King George to wrangle with.”
It certainly isn’t bible...no doubt about that, but it is a valid argument.
In sum: God’s laws and granted rights eventually compel self-defense. Not many would argue with it.
