Arguable. While English post-Reformation Protestantism was dominant, you overlook Spanish and French colonization which was entirely Roman Catholic. Maryland was a Catholic colony as were other parts of the middle and southern colonies.
LOL, America was created by a population that was less than 1/2 of 1% Catholic.
It was was founded by Protestants.
None of their colonizations were anything like the USA’s vision or success. Never mind the Monroe Doctrine and the need thereof.
