Like what kind of phony Kahanists? I am lost here. I don't know what is worse. It is said about Israel that "your destroyers come from within". I assume it means people like Yosef fake-Cohen. Who have become violent anti-semites. Unless I know who are the phony back stabbing Kahanist or what they have done, I don't know what to compare Yosef fake-Cohen to.
Have phony Kahanists threatened to kill anyone like Yosef did to Rabbi Singer?
OK people like Aryeh Eldad, Itamar Ben Gvir, Mike Guzofsky, David Haivri, etc. No they haven't (to the best of my knowledge) threatened to murder fellow Jews but they have attacked and slandered real Kahanists and in at least one case, informed on other Jews. I would not be surprised if some of the above are Shabak.
