Luther condemned the Anabaptists as heretics for denying Christian baptism. Condemned certainly , killed, sorry no. Of the Anabaptists executed, 15% were killed by secular Protestant authoruty. Guess who executed the rest?
Protestants were generally more tolerant than the Catholic authorities. Protestants were responsible for only 15% of the executions, preferring the lesser punishments of banishment or imprisonment. Many Protestant cities executed either none, or only one or two Anabaptists. Unlike some Catholic authorities, no Protestant magistrates would ever execute Anabaptists who recanted (no matter how many times they may have "recanted" before).
Anabaptist
So, again, you are wrong. Who killed the other 85%? Must have been tradition.
