Its not about refusing to open ones mind. its about you guys being able to provide the proof that natural rights are not the construct of man. I actually believe there is an intelligent force that created all things. The fact that I have that belief means nothing. The problem is that it cannot be proven. However, it can be proven that men make up rights natural or otherwise. They do it all the time. Supporting that argument is the fact men throughout history have been known to play on the emotions of the masses by using words that elicit emotional responses. "Inalienable rights" or "natural rights" are way more emotional than your "abilities". "Abilities" put the onus on the individual to do some work. Rights, especially natural or inalienable ones make you feel righteous (hmmm) and are already there requiring no work be done to have them. That in my opinion is stupid because if you don't work to keep your rights then you can lose them.
What is it exactly that man constructs? Can he construct good? Or is good a reality whether or not man constructs it? Can he construct evil or harmful? Or is evil or harmful a reality whether or not man constructs it? Can he construct captivity or freedom? Or do these things exist whether or not he understands or is aware of it?
Of course humankind confers legal rights. But legal rights are a totally different thing from unalienable rights. Even civil rights are a different thing from unalienable rights.
The Founders and the great philosophers who informed them perceived that to be free to follow one's own nature, whatever that was, was the natural state of man as it is for all creatures on earth. But because of his superior intellect, humankind is capable of intentionally limiting the freedom of other people. And humankind is also capable of embracing and respecting what freedom is--the exercise of one's unalienable or natural rights, i.e. all that requires no contribution or participation by any other.
Such exists whether or not it is recognized, whether or not it is respected, whether or not it is understood, whether or not it is allowed or decreed by manmade law.
The Founders, to a man, understood this and determined that only a man who governs himself enjoys the blessings of liberty, i.e. unalienable rights. These were defined but not limited to examples expresssed in the Declaration of Independence and in the Bill of Rights, and the purpose was to prevent the federal government from ever having power to infringe the unalienable rights of the people that existed prior to and apart from government and to secure those unalienable rights from enemies who would take them from us.
The Constitution was designed to limit all powers of the federal government and afford the people full liberty to govern themselves.
