Can’t argue with what you say but as far as I know, Thomas Jefferson was a Deist as were some of the other Founding Fathers and thus, not a member of any organized Religion.
I personally wouldn’t have a problem voting for a deist. The deists don’t falsely claim to be “Christians” while denying basic Christian truths (as the Mormon’s do). Mormon’s deny that there is one God (they believe there are many gods spread out across multiple universes). Deists also don’t have the history of falsehood, deception and violence that the Mormon church has. False church, lots of blood and shattered lives. It’s a cult.
