In his diaries from the 1930s, Victor Klemperer describes how he, a secular, thoroughly assimilated German Jew, despised Hitler. But he tried to convince people that he did so as a German; that it was his German identity that made him see Nazism as a travesty. In the end, alas, he was seen solely as a Jew.
This is the real danger of Trump’s rhetoric: It forces people who want to assimilate, who see themselves as having multiple identities, into a single box. The effects of his rhetoric have already poisoned the atmosphere. Muslim Americans are more fearful and will isolate themselves more. The broader community will know them less and trust them less. A downward spiral of segregation will set in.
The tragedy is that, unlike in Europe, Muslims in the United States are by and large well-assimilated. I remember talking to a Moroccan immigrant in Norway last year who had a brother in New York. I asked him how their experiences differed. He said, “Over here, I’ll always be a Muslim, or a Moroccan, but my brother is already an American.”
