The purpose of the poll, for me, is to discuss a debate amongst Jews. I talk with many people who declare "I'm anti-Zionist", but when I ask them "What do you think Zionist means?" they will say something like "They believe in killing Palestinians." or they will say "I don't know."
My belief is that most people, even those who say they're anti-Zionist, aren't actually anti-Zionist- it's just a word they don't know the meaning of.
