Looking at it from my particular Jewish perspective, I would agree that such concerns are irrational. Historical experience tells us that not that long ago we had an evangelical Republican in the White House for eight years, and nothing of the sort happened.
There is much more of a threat of violent antisemitism from three groups that the Democrats pander to - Moslems, radical African-Americans (e.g., Black Lives Matter), and radical Hispanics (e.g., La Raza) - than from evangelical Republicans.
So true it's worth repeating.
