Not to break anyone's bubble but slavery was very much an issue as far back as the Constitutional Convention if not before. The 13 States
(as in 13 countries) were in risk of fracture if they could not come to terms on several issues and not the least among these was the issue
of (free labor slavery) in the agricultural south. If memory serves South Carolina and The Virginia Commonwealth were the main proponents.
The compromise to gain a semblance of unity was to declare a slave as 1/2 half a person for the sake representation in the new Confederation
of States , this being prior to the Constitutional Convention. Without arguing the merits of the issue this may have resulted in a form of political
equalibrium until the northern states became industrialized to the point of having to pay labor vs the slave labor south .
As to the issue of citizens having the right to acquire or bear arms of equal lethality to those possessed by the government over them is no
less than a God given right. The Crown was perfectly OK with the colonials at Concord having a cannon and a store of arms until such time
as it was determined that we (patriots of the day) were no longer in the mood to suffer the paternalism and tresspasses of George's minions.
So out of Boston comes General Gates with his army in the dark of night and the rest is history. I would venture the Alamo is along these lines
as well. It is not the first time the powers that be have shot themselves in the foot for the purpose of curing the metaphorical ingrown toenail,,,,,,,
