You will find that all of those quotes except that of George Mason are fraudulent.

The actual Thomas Jefferson quote is, “No freeman shall be debarred the use of arms [within his own lands or tenements]“
The George Washington quote isn't found anywhere but on Second Amendment activist sites. It doesn't appear anywhere in Washington's papers. The first quote, which you attribute to Alexander Hamilton, is usually attributed to Samuel Adams. The only problem is, Adams never said it either.
That's the thing about this Second Amendment "movement", which as I said, started in the 1980s. They lie. They make stuff up. Maybe they don't realize that people can check these things, or maybe they don't care. As I said above, it tells you everything you need to know about the intellectual honesty of the pro-gun movement.
