Most Americans do not know that it was the Second Amendment that was RESPONSIBLE for the existence of the United States.
When it got down to the nitty gritty of ratification, and it looked as if there wasn't going to be a Constitution, the state's that were going to vote NO were going to do so over the right to keep and bear arms.
As difficult as it might seem in 2020, there were just as many people, percentage wise, in 1775, that thought the government should take care of all the dangerous stuff, like self-defense.
And, as much as most gun owning Americans take the Second Amendment for granted, it was a REALLY, REALLY, REALLY, REALLY close thing to it not being in the Constitution.
