The main issue is that the Progressive Left views Jews as "privileged whites"—not a minority group with a history of persecution. Despite what you've written, and the various antisemitism surveys you quote but don't link, the past few weeks have shown (me) this (antisemitism, indifference to the state of Israel) is very much a Progressive Left issue. You may call out the Right for many things, and I'd join you—But this has got nothing to do with them.
