Nice guilt-by-association fallacy. Not even a remotely workable comparison.
Unfortunately for you, there is plenty of historical support for the fact that the Reformation was just that...a reform. It was returning the people of God to the historic, Biblical faith. If you take the time to read the works of the Reformers you will find that they draw heavily from the works of those in the church who came before them.
There is no historical evidence that the Bible was the complete encyclopedia of the faith, before archeaology was as advanced as it is today it was possible to run around saying that reformers practiced ‘real Christianity’ however the more we uncover the more we find Christians practicing identically to how the Orthodox, Oriental Churches, and in most places Catholics do today.
