they are both totalitarian jew hating groups.

(far-)left groups are the same like the (far-)right ones. Political differences, ideologies.... but the same target: Israel, Zionism, Judaism... they are really against Jews, Zionism and again, and again,.. to be anti- Zionism is an umbrella to fight against, to kill Jews. Remember a lot of years ago far-right and far-left groups were trained in.... Libanon,.... to kill Jews! In Europe a lot of (extreme) right politicians, but also a lot of (extreme) left, far-left ones have parents, that were behind the Nazi- doctrine. Never forget it!
