Depends on what you mean by "guarantor," but there is no sense of that word in which a secular society can be trusted to ensure the rights of all men.

This is especially plain when one reflects that the source of all rights is God.

You evade the question with a non-sequitur. Guarantor, in this context, would refer to legal protection by law enforcement provided by the government. If man's rights are inalienable, what difference does it make what the source is believed to be? I believe that rights are derived from man's nature and you believe they are bestowed by God. If we both agree that they are inalienable, then there is no conflict. Do you believe our rights are inalienable?
