I would define zionism as the accumulation/compression of all possible prejudices against humanity into 1. It justifies murdering palestinians, theft of land, nationalization of religion, exclusivity, elitism, anarchical-capitalism, and abuse of global military, propaganda and banking systems.
This is to be distinguished from Judaism – a beautiful, peaceful religion, in which even I myself seem to find some solace every now and then.
There is a huge difference.
Zionism is murderous.
