You prove my point. Exactly!
You just said that only “citizens” are recognized as being able to bear arms. And clearly, according to Dred-Scott (and you), slaves were not recognized as citizens.
By your own argument, the whole God-Given theory of gun ownership has no weight in America.
However, you also argued (against yourself) that because the Founding Fathers themselves owned and clearly enjoyed gun ownership …
… that the FACT that individual gun ownership was not universal could be disclaimed. Sorry, dude, but just because rich white men owned guns doesn’t mean that everyone had that right at that time.
And, you just contradicted yourself (again).
Does your theory extend to murder, torture, mutilation and rape? Because that has also been “well nigh universal in that time”.
