So now we have good Jews and bad Jews, good Nazis and bad Nazis. In fact just like any other group on this planet, human or alien, that I could mention. Perhaps there are even some good people (or good reptilians) in the royal families, or amongst bankers! The lesson is that no-one can be sensibly categorised by their ethnicity, let alone the shade of their skin. Should we start looking out for bad angels and good devils?
