In truth, the deadly Inquisition tortured and slaughtered Protestants and Jews by the hundreds of thousands.
The Inquisitions began in the 12th century against the Cathars and the Waldensians. Rome then branched out to conduct the Medieval Inquisition, the Episcopal Inquisition, the Papal Inquisition, the Portuguese Inquisition, the Spanish Inquisition right up to the Roman Inquisition of the 16th century and onward to this very moment when we have Roman Catholic apologists longing for a return to Rome's blood-thirsty, murdering glory days.
Rome rewrites history. And not very well.
If thiose Protestants and Jews, and Waldensians pretended to teach and practice as Catholics, which in the earlier period was common deception.
See for example, The New Inquisition: Spanish Inquisition does not live up to reputation of injustice
You are recycling silly Protestant myths.
