If the foundation is solid, the structure will be sound

From here:

All law is the expression of someone's worldview; the American Constitution, which was set up to guarantee the protection of Individual Rights from all forms of tyranny -- was created by Christians (and a few others influenced heavily by Christianity).

Even Thomas Jefferson -- who apparently rejected the deity of Christ -- believed Christ's teachings to be the highest expression of morality and supreme to all others, used tax dollars to fund Indian education in Jesus' doctrines, and attended church services in Congress. He declared:

"The Christian religion, when divested of the rags in which they [the clergy] have enveloped it, and brought to the original purity and simplicity of it's benevolent institutor, is a religion of all others most friendly to liberty, science, and the freest expansion of the human mind."

Such a system of government depends on the moral goodness, knowledge, and vigilance of its citizens. The recently-accelerated usurpation of our Constitution by power-hungry and condescending elected and judicial tyrants -- who believe that We the People exist to provide them power and position, rather than understanding that their position exists to protect our liberties -- is due not to any fault in our Constitution, but to the American people's ignorance, negligence, and greed.

By contrast, shari'a (Islamic law) -- which sacralizes and institutionalizes the vilest of atrocities, including pedophilia, torture, mutilation, slavery, rape, murder, wife-beating, polygyny, and religious and gender apartheid -- is founded on the words and deeds of Muhammad, whose example is considered by Allah a "beautiful pattern of conduct" for those who want to please it. This is why no Islamic nation with any form of shari'a enjoys spiritual, cultural, philosophical, moral, technological, or material prosperity, and those non-Muslim nations with Muslim populations of any significance endure constant turmoil, depredations, and every form of insecurity.
