Trump's poorly-executed "Muslim Ban" has closed the United States to people from seven majority-Muslim countries, including refugees from Syria, Iraq, Yemen and Somalia. But the divisive "them" and "us" rhetoric of the White House has had repercussions for other groups as well.
Jewish people have not explicitly been the focus of any kind of executive order (after complaints about his lack of action, Trump called anti-Semitism "horrible"). Nevertheless, the new administrations appears to be implicitly pandering to anti-Jewish sentiment.
Take, for example, the official White House tribute issued on Holocaust Memorial Day in January. It failed to directly mention Jewish people at all. Jewish groups, including those representing Republicans, criticised the omission. Trump's chief of staff Reince Priebus defended the statement, saying: "I mean, everyone’s suffering in the Holocaust, including, obviously, all of the Jewish people.”
Superficially, one could attribute this to ignorance. But how politicians phrase their words matters. It is a common tendency of anti-Semites to play down, ignore or reject the idea that the Holocaust was targeted at Jews. It is hard to believe that no one within the White House would have been aware of the kind of dog whistle this omission sent to the extreme right.
That White House staff includes Trump's chief strategist, Steve Bannon, who was the executive chairman of Breitbart, viewed widely as the online news outlet of the "alt right".
Timing also matters. The decision to shut US doors to Syrian and and Iraqi refugees was announced on Holocaust Memorial Day. The irony of an order singling people out for their faith wasn't lost on Jewish groups, who know all too well how many German Jews fleeing the Nazis were turned away from other shores. Trump's response time sent a message too. When a Hasidic Jewish reporter asked Trump about the growing anti-Semitism at his press conference on 16 February, he responded as if it was a personal attack, calling the question "very insulting" and telling him to sit down. Despite tweeting vociferously about Saturday Night Live and his daughter’s clothing line being dropped by a department store, Trump only managed to issue a statement condemning anti-Semitism on Tuesday.
David Samuels is a prominent Jewish writer living in Brooklyn, New York. He told me: "American Jews are threatened by rising anti-Semitism on both the right and left, which FBI statistics show to be more serious and more deadly than any animus directed towards Muslims or any other religious group.
"I feel sad that this is now my country, not because I am Jewish but because anti-Semitism is a degenerative thought-virus that makes people crazy by promising to explain everything that happens in the world with reference to a single prime mover - the Jews.
"Because anti-Semitism is a conspiracy theory, and not a form of social prejudice, it is fatal to rational thinking, in a way that simple racial or religious prejudice - including prejudice against Jews - is not."
Whatever the intentions of the Trump administration, the reaction in the country at large shows it is playing with fire. Americans must hope that Trump, who has three Jewish grandchildren, will come to his senses and rid his support base of any who seek to use the presidency to infect the country with their diabolical ideology.
