Simone Zimmerman, is one of the film Israelism's main subjects and a co-founder of the group IfNotNow, says she grew up being told that supporting Israel was central to her Jewish identity, but that collapsed once she visited the Occupied Palestinian Territories and saw the system of apartheid under which millions live. “It’s so deeply contrary to our values as Jewish people to support this disgusting oppression and denial of freedom,” she says. Simone was once as Zionist as you can get. I strongly suggest seeing the film: Israelism.
