Two observations based on recent events:
#1 The wave of anti-Semitic hate spreading around the world right now is frightening. To any objective observer it should be clear that President Trump is the strongest supporter of the Jewish people we’ve ever had leading the free world. The worst thing the left could say with any credibility is that his support for Jerusalem might anger anti-Semites, but we don’t make decisions based on the heckler’s veto.
What is causing this rise in anti-Semitism? Who are the biggest threats? Muslim extremists? White Nationalists? Could it be that those on the political left are the leading cause of anti-Semitism by their constant verbal attacks on Israel, which paint them as the oppressors and the Palestinians as the heroes? I think so; at least they have the biggest voice, since they control most of the media.
#2 The kind of violence we have seen lately (the massacre in Pittsburgh, the vandalism of a synagogue in Irvine, CA) plays into the hands of liberals and their attempts to blame conservatives for Anti-Semitism, even though an increasing part of it is coming from liberals. But we do occasionally see anti-Semitic expressions and actions on the part of people who otherwise identify as political conservatives. So I strongly wish that conservatives could disown and disavow anti-Semites once and for all.
I look at the Pittsburgh shooter and I wonder what did a Jew or Jews collectively ever do to this man to make him hate so much? The answer is probably nothing; it's just that he filled his head with all sorts of bizarre conspiracy theories. Life dealt him a bad hand, and he had to blame somebody. But this kind of insane violence isn't the constitutional republic we call America; and principled conservatives need to drive a stake through the heart of this evil so it no longer rears its ugly head.
