Sadly the events of October 7th have more than made it clear how truly alone people who are Jewish. On the one hand, the left has made it very clear that their position on Israel and its collective fate has absolutely no incongruity with their position against Trump. Somehow they can admonish him for saying that there were 'good people at Charlottesville' and in the same breath chant from the river to the sea which is the Palestinian version of Jews will not replace us. One recent leftist magazine argued how they can fight anti-semitism without having to stop being anti-Israel.
And on on the far right are people not merely like the one you discuss but who believe that the only benchmark for Judiasm is reliant on your complete and utter support for Israel with no criticism at all. In their minds to be disloyal to Israel is the only thing that makes a person Jewish and criticizing the Israeli government is just as offensive as criticizing Trump.
What is clear to the extremists both sides, sadly, is that they alone are the arbiters of what it means to be a Jew in America. The polarization of our society has made poltiical identity trump (and no this is not a play on words) all other parts of it. Your political affiliation must be more important then your racr, religion, gender and overshadow even your family affiliations. We always knew it was underlying the far right; to see the left - the 'good guys' take this attitude has been the rudest awakening of the last year for me. And as this site has demonstrated time again, just like the far right, the far left will do anything to see the problems in the world but look in the mirror.
