Your position on the scope and presence of Deism in early America is way overstated.
Like their English counterparts, most colonial deists downplayed their distance from their orthodox neighbors. Confined to a small number of educated and generally wealthy elites, colonial deism was a largely private affair that sought to fly below the radar. Benjamin Franklin had been much taken with deist doctrines in his youth and had even published a treatise [A Dissertation on Liberty and Necessity, Pleasure and Pain] in England on determinism with strong atheistic overtones. But Franklin quickly repented of his action and tried to suppress the distribution of his publication, considering it one of the greatest errors of his youth. Henceforth he kept his religious convictions to himself and his clubbical “pot companions” or drinking friends, and tried to present as orthodox a public appearance as possible. Like his handful of fellow colonial deists, Franklin kept a low theological profile. As a result, deism had very little impact in early America up through the American Revolution.
