As I’ve told you before, Abu Chand, If Jews today are descended from 8th century CE Khazars, then surely they could not have betrayed Jesus in the 1st century, nor killed any of the prophets, the last of whom might have been Mohammed, 7th century CE. It follows that the actually perpetrators were both Muslims and Palestinians.
But then antisemitism such as the Khazar myth you profess is hardly logical. The ancestors of many if not most of today’s Palestinians migrated to the region from Europe and elsewhere in the middle east, but it would no sense to attack them because of their Egyptian, Jordanian, Iraqi, Frankish, Kurdish or Byzantine ancestry.
