Youre argument from day one is that Israel never did what it ahs been see to do over and over again - not responsible for massacres, Sabra Shatila, killing of civilians.

I have put Israel's case as you have put the opposite case.
Why do you object to both sides being put?

castigating Israel for occupation and terrorism.

No. He has not castigated Israel for terrorism. Why claim it?
He did refer to "occupation." That is an interpretation of the situation, but many do not share it.

"No. You can't"
Ah, familiar territory.

Familiar yes.
When Jim accuses me of saying things I never have and never would say, I point out that he is lying again and can not give a quote because it is a lie.

I ask Jim to respond to what I say and not lie that I have said things that I have not said.
I ask that he debates the issues instead of trying to demonize me personally with lies.
Reasonable request I think.
