Of course there were and are black Jews. Jews don’t want to be associated historically with black anything. So they change their history to adapt to their agendas. Most Jews just follow the group and have been taught not to question.
Jews call Palestinians black and Jews living in Palestine claim that land as theirs. So if their land grabs are based on Palestine being their homeland and Palestinians being black, how is it that Jews aren’t black?
Wherever there are Blacks and Jews, there are Black Jews. That’s how they spread themselves throughout the world without being counted, so they can maintain their tiny minority status.
