There is some truth to the statement, but the Reformation was a process, yet in need of continuance, as many things from Rome that had to be unlearned, and it was those who in conscience toward God dissented from the status quo, RC or Protestant, that were most notable leaders.
And evangelical faith, despite or partly because of its diversity, was largely responsible for the moral reformation and great revivals that worked to make America the a Christian nation in the degree that it was. And rejection of Christian faith and morals is costing it greatly in souls, lives and money.
