Gun is a MAN MADE right. Even freedom of religion is a man made right.
I'm surprised no one else called you on this... it's terribly ignorant of the minds of the Founding Fathers. You can read their minds in the Declaration of Independence, Constitution and Federalist Papers to see that they understood very well the Natural Law in that man does not confer rights to each other. Each person has inalienable rights endowed in us by our Creator. The only thing man can do is allow or restrict our exercise of these rights.
What is "man-made" is government. To this government, man has conferred certain and defined powers and authorities for the common good.
