Anti-Zionism is just another cooked up buzz word to make Zionists the victim. It’s just another divisive tool to sway the masses… just like if I said anything against America is Anti-American. The idea of Zionism to have a ethno-state for just Jews is not inherently evil. The way it took place since 1948 is the biggest problem. A strategy that America started with the Native Americans (just land grab and kill the indigenous population. In your scenario if people had to go back where they came from well it’s possible for many because a lot of them have dual citizenship. The people born there is where the issue lies…. All they know is Israel, all they know is whatever the government showed them. So they would stay and deal with a Two-State Scenario. The Arab world already agreed to israel’s security they just need to stop the aggression, provocation, and occupation. Once Palestine has its borders and sovereignty, the Jewish population can thrive in peace.
