So in America in the 21st century, white Jews are treated pretty much like any other white person. I would say that there are some subtle cultural things that make me feel a bit "other", though. For example, sports teams called the "Crusaders": In the Jewish collective memory, the Crusades were an awful time. Crusaders rampaged through many Jewish communities, murdering many thousand of Jewish people and destroying the Jewish communities in several cities (cf. https://en.wikipedia.org/wiki/Rhineland_massacres, among others). There are historical records of Jews committing suicide in anticipation of the Crusaders reaching their cities. Hearing about basketball teams called "The Crusaders" really surprised me -- did these people not know what the Crusaders did?
