Really? The Eastern Orthodox Church would like to have a word! You also leave out the Arians, Monophystes and other movements that didn't accept the Catholic/Orthodox view on things.
Have you looked at the world?
Uh, a Church that worked for German people instead of Austrians wasn't exactly radical. A lot of Germans actually liked that.
Actually, the Catholics did far more oppressing. Ever hear of Bloody Mary? Or the St. Bartholomew's Day Massacre? The Spanish Inquisition?
Again, Bloody Mary. People murdering each other to pacify an imaginary sky pixie is a little silly.
I think you don't really understand why the English Reformation happened. It happened because by the time of Henry VIII, the Church owned half the land in Europe, engaged in all manner of corruption. And they could have kept doing it, all they had to do was grant Henry his very sensible ask for an annulment. They gave one to his sister. But his soon-to-be ex-wife's nephew had an army double parked outside Rome, and the Pope was immune to the usual bribes to shake down people for annulments.
If you are reading history to feel good, you aren't reading history, you are reading propaganda.
