To 'spell it out' for those who still can't wrap their heads around it:
What Israel is trying to claim (which is a logical fallacy): Any attack/criticism on Israel = attacking Jewish people = attack on Jewish/Judaism religion
The reality: Any criticism Attack on Israel =/= attacking Jewish people =/= attack Jewish/Judaism religion
So what about those that practice Judaism in Gaza? What about those that practice Judaism that has no roots in Israel at all?
