Just a couple of comments:
First, it’s unclear to me why and how you would propose “love” to combat this hate. The foreign intervention and Jewish bravery that you credit with defeating the original Nazis didn’t use love as its weapon — certainly not love of Nazis.
Second, while I have no knowledge of what’s going on in white-sheet-land today, I have no problem positing that there’s plenty of antisemitism among Trump supporters. It’s strange to imply by omission, though, that the Left doesn’t have its own deep bench of Jew-hatred, complete with calls to kill Jews, Holocaust denial and the whole “playbook” you refer to. I don’t think that finding the specific moral weight of the Democratic Party and comparing it to the specific moral weight of the Republican Party is an interesting or useful endeavor, but there’s something distasteful about using the serious issue of dangerous hatred to bludgeon one’s political opponents — especially when it allows a large group of haters to not-only get off scot free but pat themselves on the back while doing it.
