I read that anti-semitism has been on the rise in the United States since 2015, and now we have had 66 bomb threats to Jewish facilities so far this year — and it’s only the end of February. These bomb threats are only the tip of the iceberg. The less dramatic but equally harmful manifestations of anti-semitism are numerous and so rapidly growing in number that many in the Jewish community feel we have reached a crisis. Who will provide the leadership to counter this scandalous trend? The President has been quiet about it. His single declaration that “anti-Semitism is horrible and it’s going to stop and it has to stop” is typical bluster. His PR people tell us that Mr. Trump cannot be anti-Semitic himself because one of his daughters is Jewish. This is a silly argument, but let’s let it go. The real issue is not whether the President is at all anti-Semitic, but the fact that many of his supporters surely are. He does not speak out regularly and energetically against anti-Semitism because to do so would alienate many of those who now support him feverishly, people who have been invited by Trump’s statements and his silences to “come out” with their prejudices and phobias.
