Good point, just the kind that makes liberals get red in the face and hurl ad hominum insults.
But since 2A was clearly written to allow us to protect ourselves against tyranny, then it is obvious that if potential tyrants progress past muskets, then we as a people who wish to remain free must also progress past muskets.
And that brings us back to why lefties really want to disarm us. Crime stats don't back them up, never have. But since they can't publicly admit that they really are afraid of free men having the capability of resisting tyranny, they blame crime on gun owning NON criminals, i.e. free men.
All leftists are believers in tyranny....with them as the rulers, the chosen ones.
I have leftists in my family. It is clear, they would sell their first child ( most think the world is over populated) to advance their agenda.
