Drawing comparisons of contemporary Israeli policy to that of the Nazis.
Jim C does that.

    Applying double standards by requiring of it a behavior not expected or demanded of any other democratic nation.

Don, you have endlessly criticised Israel for their perceived ill treatment of Bedouin, but you have never once criticised Egypt for their actual persecution and marginalisation of them, denying them even basic citizenship and employment rights.
Nothing to do with Zionism there.

You have frequently denounced Israel for other perceived crimes but never their Arab neighbours Syria, Gaza, Egypt or Jordan.
Again, not Zionism but favouring any state over the Jewish one.
