I agree with the guy in the video (in the yellow shirt), more than the narrator. The Constitution is a recognition of our rights and it does matter what it says. If there comes a time when our government manages to change the 2nd amendment, let’s all hope they simply clarify it with more verbiage and not change the essential meaning as originally intended.
Since the Constitution is the foundation of our government, it really matters what it says. We are lucky not to live in one of the British Colonies, since their people really are subjects of the government, and thus, have no natural rights - they only have the rights their government gives them. But for USA citizens, we do have natural rights, but they must be framed correctly (as our Constitution does), or our natural rights could be changed, or even reduced, in writing, such that those rights are no longer recognized same as before.
