So not true. Off the top of my head, I can think of the destruction, beatings, burnings, murders, and other atrocities that took place in Calvinist Switzerland. My favorite spiritual writer was threatened with death on a number of occasions as he traveled through that region trying to convert people back to the One, Holy, Catholic, and Apostolic Church. But he remained steadfast, preaching and passing out religious tracts, and ended up converting thousands (72,000 approximately) of people back.
