"you havne't heard of christians terrorizing jews at any time over the past century,maybe more? (your initial phrasing of the time period)"
You don't seem able to differentiate between people who are Christians and The Christian Faith. Muslim LEADERS, Imams etc themselves despise and want to kill the Jews. When was the last time, if ever, Christians were inveighed from the pulpit and or the throne of St Peter to wipe the Jews (as subhumans, monkeys etc) off the face of the earth?
For muslims it is an unbroken wail from the first moment of the DeathCult to this moment.
Crusades are the best example. Pre-Vatican 2 liturgy held that Jews collectively bear the guilt for Christ's crucifixion.
