I have faith in God and confidence in the basic principles upon which the country is founded.
The Constitution is an expression of a
lack of faith in people, irrespective of their labels
du jour.
Your bogus rate of fire argument is a (perhaps not deliberate) attempt to distract from the 2A's
absolute right of self defense.
The NRA is so strong, and the blowback against gungrabbers so strident, because
nobody is buying the 'boil the frog' argument. The Left is understood to argue in bad faith, because the Left ultimately hates liberty and wishes to reduce a free people to livestock.
And why is it that on other matters you are fine to leave the states and jurisdictions to pass their own laws, but on this particular situation you want the federal government to step in and tell the smaller governments how to do their jobs?
Let's flip that around, and inquire why the 14th Amendment has been used to incorporate the entire Bill of Rights except the 2A, against the smaller governments?
Hint: "educe a free people to livestock" is the ultimate goal.
