and yet, Christians persecuted Jews in the Middle Ages....Muslims took over when they stopped...
Christians extremely persecuted the Jews twice in the first half of the 20th century, not just in the Middle Ages. We may all question whether the Christians that killed millions of Jews were really Christians, but we could also question whether the Muslims who killed thousands of Jews are really Muslims.
Anyway, the Christians committed not just the Holocaust, but also the Pogroms(which was split between the second half of the 19th century, and the first half of the 20th century).
Jewish history is just littered with genocide by Christians.
