@coded_artist @lovelymiss Kevin McDonald called this "boiling off". Generations of living amongst gentiles meant that any that had problems with their scheming, lying, cheating, and murder, would have left them. In many cases that did happen, like in the disputation of Paris:
"The debate started on 12 June 1240. Nicholas Donin, a member of the Franciscan Order and a Jewish convert to Christianity, represented the Christian side. He had translated statements by Talmudic sages and pressed 35 charges against the Talmud as a whole to Pope Gregory IX by quoting a series of allegedly blasphemous passages about Christianity. He also selected what he said were injunctions of Talmudic sages permitting Jews to kill non-Jews, to deceive Christians, and to break promises made to them without scruples. [...]"
"The Catholic Church had shown little interest in the Talmud until Donin presented his translation to Gregory IX. The Pope was surprised that the Jews relied on texts other than the Torah, and that those other texts contained alleged blasphemies against Christianity."
