Utterly Mad

The second amendment was literally because we had no standing army so we needed any able bodied man(because back than America was sexist...it's history get over it). It was never about hunting, but to protect the nation from any invading force, and I mean ANY invading force. We were scared of the British, but IIRC we were also very scared of anyone trying to attack us since we were the figurative 'new kid' on the block as far as nations went and we didn't have any real international ties.
Also the Wild West was exaggerated by the people living there to sell things. Yes they had issues with Native Americans and bandits, but to a much lesser extent than people were led to believe. These things happened rarely, literally our modern mythos about the Wild West was made to sell things and travelling shows.

Two years of college grade history classes, a Federal Government class, and some personal study on some topics have given me an amount of knowledge on subjects that no one cares about. I may be wrong on the whole 'scared of anyone' thing, but If I recall correctly that was brought up in one of my history courses.
