Load of horse-crap.
Sorry, but we don't need to be deprogrammed out of our Zionism. Most Jews are Zionists, not because they've been brainwashed but because they believe in the idea of self-determination in our ancestral homeland. That's all Zionism is. Everything else you hear about it is nothing but propaganda designed to vilify it.
Anyone who claims to believe in ethnic self-determination should support Zionism. And those of you who don't might want to reflect on why you support ethnic nationalism for Palestinians but not for Jews.
