It's an absurdity, but it's no more absurd than believing in Bigfoot, or that the world was created in 7 days 6,000 years ago, or that eating shellfish will send you to hell.
Most of these beliefs are harmless if held and practiced in private. When one group tries to impose its superstitions upon others using the force of government, however, problems arise.
We may not know what the Founding Fathers would have thought about everything - but as products of the Enlightenment, we do know they were 100% flat-out against theocracy and superstition. Their view of the world was informed by the devastating factional religious wars of 16th-18th Century Europe, and they concluded that the fusion of state and religion is not what they wanted for our country.
How do we know that? They told us, many times, and they put it into the First Amendment.
If y'all want to found a mental MAGA-stan which hearkens back to pre-Enlightenment ways of thinking, go for it - but recognize that it's fundamentally un-American, and we ain't coming.
