USHMM:

The shocking eruption of antisemitism on many American college and university campuses is unacceptable and university and all other appropriate authorities must take greater action to protect Jewish students. Demonstrators at Columbia University calling for Jews to return to Poland — where three million Jewish men, women, and children were murdered by the Nazis and their collaborators — is an outrageous insult to Holocaust memory, a failure to appreciate its lessons, and an act of dangerous antisemitism.

America is hardly the Third Reich, but the Holocaust teaches the dangers of pervasive societal antisemitism, and awareness of this history must guide our actions in the present. Nazi ideology was official state policy, but it found a receptive audience on university campuses based on well established contempt towards Jews.
