I am not familiar with the specific case, my answer was meant in general.
EDIT: I think it was historically the situation that when Nazis (the real ones, i.e. the NSDAP Nazis, not the people who disagree with me “Nazis”) were losing a political debate, they often changed the rules of the game, and attacked their opponents physically (“pigeon chess”). Which is why everyone else developed a rule “if Nazis invite you to a debate, you don’t participate (or you come ready to throw punches, if necessary)”. No idea whether this is a fact or a myth.
