The writer of the link makes a constitutional point that is in some ways remedial. That is, many people believe, wrongly, that it is a founding principle of our country that human rights are given by government.
The idea that rights pre-exist government or the Constitution strikes such people as unfathomable. When challenged, they are likely to say that human rights are limited, especially that society at large has superceding interests that must constrain the natural rights of individuals.
Hogwash. The whole concept of America is that individual human rights are unalienable.
