We have to allow the Nazis to speak or else we're racist against white people!
This has absolutely nothing to do with them being Jewish. It has to do with them being complicit in a genocide. Zionists can be Jewish or not and Jews can be Zionists or not. They aren't the same thing.
The specific Zionists you are accusing of genocide are themselves Jews, specifically Jews who are the children and grandchildren of holocaust survivors.
