Ok.
you’re wrong
Not really.
Thomas Muentzer was one of the original lights of the Anabaptist movement, and he led a bloody rebellion in Thuringia against the local authorities.
The Anabaptist leader John of Leyden led an assault on the town of Muenster and declared himself King, exiling and even killing those who disagreed with his beliefs.
Hendrik Of Nicholis - another prominent Anabaptist theologian - was a supporter and participant in the Muenster regime.
After the Bocholt conference, the Anabaptist movement split, with one-third led by Jan von Batenberg advocating violence against unbelievers, one-third following David Joris' advocacy of assimilating into the the larger world and one-third following Menno Simons who advocated peaceful retreat from society.
Batenberg's followers - all devout Anabaptists - became 16th century terrorists, striking at the infidels and killing and robbing them.
Batenberg's disciple Cornelius Appelman, who took over the movement after Batenberg's death, continued this policy. Appelman killed his own wife and daughter when they adopted what he beleived to be heretical views.
Johan Willemsz was another incredibly violent Anabaptist leader of that time.
Historians of the Radical reformation like Jansma have documented how the more violent Anabaptists like the Batenbergers and Willemszites, when heat from the authorities against them became too intense, hid among the Mennonites until the coast was clear or the mennonites were able to secretly transport them to other jurisdictions.
