Why people are drawn to cite the words contained in a Divorce Decree (aka Declaration of Independence), declare those words to be the ultimate gospel that all must abide by, is beyond me. Natural rights are far from being the building blocks of our country.
You realize that natural rights are a myth based on the premise that some deity grants humans rights, which humans can't alter, diminish, or dismantle. In other words, each individual's social behaviors are "based on their perception" of what a specific right means to them personally. We've got enough problems in the world without attempting to put in practice a mythological rights theory.
There is absolutely no way to instill a common meaning or clear definition of a specific right, which results in common behaviors, which produce common outcomes across all populations, cultures, races, religious beliefs, etc, etc, because of the fact that "such rights exist, by perception only, in the minds of each individual".
In reality....
Natural rights amounts to people being self-will-run-riot.
The Natural rights theory is fundamentally the claim that individuals are free to exercise or engaging in personal and social behaviors "within the confines of what they personally believe a given right entails", or how an individual defines the privileges contained with a given right - while respecting the rights of others to act on their individual perceptions, while engaging in their individual beliefs of what constitutes non-infringing behaviors. <<--- This is total nonsense.
We live in a world of individuals who are actually worlds unto themselves, who to some degree, believe that their perception of the universe, and all things contained within, are the "correct perceptions". Any society that would adopt such a Rights theory as the blueprint for maintaining any successful level of order, you can take it to the bank that social chaos is unavoidable. You can expect to see frequent infringements on "the perceived rights of others", by most, if not all individuals, whether their actions or behaviors are deliberate or not.
