Nazis and Jews are not alike in any way. Those people who say or believe that Nazis and Jews are alike are not only wrong, they are intolerant and bigoted. Nazis, the followers of Adolph Hitler, discriminated against Jews, and murdered or tortured many Jews in the Holocaust. Ask any Holocaust survivor, and they will tell you how the Nazis harmed the Jews. They will also tell you that Jews are not Nazis, and are not like the Nazis in any way.
