To be marginalized means to be an outsider because of differences. Marginalized groups are also considered minorities. When Hitler came into power one of the groups he marginalized were the Jews. There were many different ways he did this.  One way was by holding antisemetic rallies. He also blamed them for many of Germany’s problems. Another thing he did was he forced many Jewish owned businesses to close. Then, he made Storm troopers(Nazi police) make arrests on Jewish people for no reason. Finally, he would have his Storm troopers go and randomly beat up Jewish people. This all shows that he marginalized Jewish people because he said and made Nazis do things that would make Jews feel like and be outsiders in Germany.
