Why did they come up with the name "Zionist union"?
The best way to combat what everyone knew - that they are not zionists - is to state the opposite of reality and then the big lie gets some credibility and traction.
Zionists don't ally themselves with Hezbollah supporters
If you are a leftist that still cares about Israel, you need to wake up and smell the coffee
You must decide: do you care more about Israel or do you care more about leftism?

this man does not simply disagree with certain policies of the state.
he supports the enemies of the state, enemies who have vowed
to destroy the state itself.
these enemies, iran, hezbollah, hamas, all islamist terrorists, murder
members of the civilian population and carry out wars of aggression
against israel. these islamist terrorists use incindiary weapons, terror
tunnels, missiles, to try to destroy israel. they will not succeed.

The problem starts with Kalisch-Rotem herself, and her willingness to serve as Trojan Horse for the enemies of Israel.
