Christian history of hatred for Jews has always been murderous, from the crusaders to the Kazaks, culminating in the Holocaust. After that shame and the triumphant founding of the modern State of Israel, many Christians woke up and have become allies. Some have even stopped missionary activity toward Jews, but none have returned their captives. Some Muslims in Christian countries seem better at befriending Jews. There are quite some troubling texts about Jews in the Christian Bible.
Muslim history of hatred for Jews has been mostly one of disdain, rape, and exploitation. Only with the expansion of the number of Jews in Zion, Muslim anti-Semitism became murderous too. Thank G^d, the Holocaust did not get a Muslim counterpart but with it, Muslim awareness of the shamefulness of their hate isn’t great. They’re largely unashamed about it. There never were many free Jewish conversions to Islam but many of the Jews in Palestine, a few centuries ago, were forcibly converted to Islam. Conversion ended the hatred. Their animosity was not racial. Descendants of the converts are still hiding among Palestinian Muslims. Some Christians in Muslim countries seem better at befriending Jews. The Koran has both very negative and very positive texts about Jews.
Formerly Christian societies (Stalinism) murdered Jews with impunity too. European secular descendants often show again this deep hatred.
Asian non-Monotheists have no animosity toward Jews at all. If this would have been well-known eighty years ago, more European Jews could have found a safe haven in Asia, escaping the Holocaust.
Jews always knew sporadic friendly Christian individuals and rulers.
Jews always knew sporadic individual Muslim friends and peaceful epochs in Muslim society, like in Spain until the Christian occupation and in Iraq until the founding of Israel.
Western Christian disrespect for Muslims does not help and betrays a lack of humility and of certainty about their own religion. Instead, Christians should go to teach Muslims their understanding after the Holocaust and should hope to learn something in return about what is real Monotheism. If Christian and Muslim Jew-haters could band together, certainly, Christian and Muslim friends of Jews could do so.
