It's a horrible curse spelled and started by the Roman Empire that renders Jews as the culturally inherited suspect for potentially everything. My suspicion for why this is, is, that Christianity was forced on Europe and so were the ideas of the Middle Easterners. But, of course, as primitive and comparatively savage as those times were, people would choose an easy victim, someone who supposedly started it all. Of course it was not Rome, because most had to surrender to it. Of course it wasn't the Greeks either, because they were Rome's toothless grandpa. It has had to be someone outside and yet close. Someone who has been victimized before, utilizing the same rationalizations. The anger and desire of revenge for getting romanized never ceased. It chose the path of the lowest resistence which lead to the Jews. The path of the coward has lead to this.
