Yes, that’s right: homosexuals, witches and those they regarded as heretics. While the Catholics, esp. under the Spanish Inquisition, did plenty of that, the Protestants did also - even by burning! Such as John Calvin, that theocratic tyrant:
‘The secular officials were unable to establish that Servetus was an immoral disturber of the public peace. Nevertheless, he made damaging theological statements in the course of a written debate with Calvin. The Council of Geneva, after receiving the advice of churches in four other Swiss cities, convicted Servetus of antitrinitarianism and opposition to child baptism. Calvin asked that Servetus be mercifully beheaded. The Council insisted he should be burned at the stake.
‘The execution: Spectators were impressed by the tenacity of Servetus’s faith. Perishing in the flames, he is said to have cried out, “O Jesus, Son of the Eternal God, have pity on me!” Farel, who witnessed the execution, observed that Servetus, defiant to the last, might have been saved had he but called upon “Jesus, the Eternal Son.” A few months later Servetus was again executed, this time in effigy, by the Inquisition in France.
‘Many Protestants approved the Genevan sentence. Others, especially in Basel, were not so sure that heretics ought to be put to death. In answer to critics, Calvin quickly put together and published, in 1554, a justification, Defensio orthodoxae fidei, contra prodigiosos errores Michaelis Serveti Hispani (Defense of Orthodox Faith against the Monstrous Errors of the Spaniard Michael Servetus). He argued that to spare Servetus would have been to endanger the souls of many. In the same year Calvin was answered by Sebastian Castellio, in Contra libellum Calvini (Against Calvin's Booklet). Castellio declared that “to kill a man is not to protect a doctrine; it is but to kill a man. When the Genevans killed Servetus, they did not defend a doctrine; they but killed a man.” He said that “if Servetus had wished to kill Calvin, the Magistrate would properly have defended Calvin. But when Servetus fought with reasons and writings, he should have been repulsed by reasons and writings.”’
