> Are Zionists fascists, and (religious) racists?

Muslim Brotherhood is a coherent organisation, so we can meaningfully talk about its beliefs. Asking whether "Zionists" are fascist is as incohrent as asking if Antifa "believes" in anything. These aren't coherent organisations, just loose collections of aligned folks.

Fundamentally, nothing about Zionism strikes me as requiring fascism or religious supremacy (though it does require religious segregation).

How antisemitic. You aren’t allowed to critique them. Yes even if they rape their prisoners and defend their rapists in parliament and on TV.
