There would be no backlash because they have brainwashed the Zionist so called Christians into believing that the Ashkenazi and Sephardic "Jews" are really Jewish and that the Jewish god has commanded them to exterminate every single Palestinian
Zionists have been fault finding the State of Israel for not exterminating them yet
In reality if there was a historical person named Jacob who was renamed Israel then the Palestinians have the highest percent ancestry from Israel
