Back to the point.
The founders created our country based on their worldview that there is indeed a Creator, and our rights come from that Creator, and are inviolable by the institutions of Man.
Now, if you don’t think this is a given, then you have no basis for declaring that you have any inviolable rights.
That fact that this was their worldview does not make it true. Until objective evidence shows the existence of inviolable rights, their existence remains an assertion. In the meantime we can continue to operate as if they existed.
Which they may. Or may not.
