I suspect it is not a person but a group or organisation based at some university. And I have an horrible suspicion it is an anti-Semitic entity. Did you notice he blamed the Arabs for being Hitler's buddies? Not the Palestinians but if 'he' knows half as much as 'he' pretends he will know about the Palestinian SS groups. Fairly common on pro-Palestinian sites. For an example, look at how Linda Sasour does it.

My objective is to warn 'his' target audience that 'he' isn't all he seems. I pick on things 'he' says and show it for the poor reasoning it is. I then drag 'him' down the rabbit hole until nobody is following the conversation any more. This wastes 'his' time.

I fight for Jews as a matter of life and death. 'Never again' for me means, never again. 'He' fights against Jews because 'he' is a privileged bored child.
