Leftists like Abe "Twentieth Century" Foxman don't believe in unique nationhood. No one is forcing Arabs and self-hating Far Leftists and the Neturei Karta to remain in Israel. If they don't like Zionism, they're free to move to a country where they don't have to commit to it. That's the point with the loyalty oath. Israel was founded on a set of principles and either one identifies with them or gets the hell out of Dodge.
"Show me just what Mohammed brought that was new, and there you will find things only evil and inhuman, such as his command to spread by the sword the faith he preached." - Manuel II Palelologus
Were there Jews who supported Hitler in the 1933 election thinking “aww, gosh he can’t possibly be serious, he’s just saying all this stuff about us to win votes”?
I’m Jewish btw.
