Martin Luther was a fascist
Martin Luther was an anti-semite. He hated the Jews.
In 1543, Luther wrote 'On the Jews and Their Lies' (German: Von den Juden und ihren Lügen), in which he advocated harsh persecution of the Jewish people.
Luther wrote that Jews are devils, blasphemers, and liars who "lie so clumsily and ineptly that anyone who is just a little observant can easily detect it," a "miserable, blind and senseless" people, "nothing but thieves and robbers who daily eat no morsel and wear no thread of clothing which they have not stolen and pilfered from us by means of their accursed usury." (On the Jews and Their Lies (Martin Luther) - The Wikipedia Review)
Luther seemed to support adultery. Luther said that a woman had the right to take on a lover, if her husband wasn't able to satisfy her in bed. ( Martin Luther . Cheat's Guide PBS)
Luther could be crude. He is reported to have shouted at the devil: "I have shit in my pants, and you can hang them around your neck and wipe your mouth with it." Luther believed he could drive the devil away "with a single fart." (Wallace et.al., The Intimate Sex Lives of Famous People: p281 Rejection of Pascal's Wager: Martin Luther)
Luther wanted witches to be killed. Luther declared that a possessed child should be thrown into the river to be killed or cured. (Robertson, History of Christianity: p208 Rejection of Pascal's Wager: Martin Luther)
Luther could be considered a fascist. He supported Serfdom.
Luther encouraged the nobles to suppress the 1525 Peasant's Revolt in Germany by violent means. And in fact the nobles tortured and then killed over 100,000 peasants.
Luther wrote: "Let all who are able, cut them down, slaughter and stab them, openly or in secret, and remember that there is nothing more poisonous, noxious and utterly devilish than a rebel." (Rejection of Pascal's Wager: Martin Luther)
To Luther, the abolition of Serfdom was "against the gospels".
