Tell that to the Cathars
The protestants were vicious to the Catholics in St. Elizabeth’s England (1585 Penal Laws and the killing of priests) and the Puritans and other protestants persecuted (including the burning of Churches) Catholics in the New World.
Can we talk about the deliberate starvation of 1.5 million Catholic Irish at the hands of the British protestants?
These sad eras are due to original sin and its effects on all of mankind - Catholics are no worse than Protestants and all are subject to original sin.
