Maybe. My guess is that there were many hatreds among our distant progenitors long before there were Jews. However, there is no doubt that hatred of the Jew has now become one of the few hatreds which can be proudly displayed in public.
There is a chicken & egg problem – which is the driver in the minds of today’s Far Lefties? Do they hate Jews because of Israel, or hate Israel because of the Jews?
What we do see in the behavior of the Usual Suspects is that they lionize the under-performer – the disabled, the trans-gendered, the illegal alien. The problem for both Israel and Jews is that they are over-performers – and therefore bad.
