It's not shocking to me. I've been saying this is coming for years. Try wearing a yarmulke on any college campus and see what happens. Try going on any college campus with an Israeli flag on your backpack, or a star of David bumper sticker. Antisemitism on the Left is virulent and openly violent. The modern Left considers antisemitism and anti-Christian thoughts and acts to be, not a hate-crime, but rather it is virtuous. It is 'enlightened thought'.
And Jews are not exempt. Some of the most antisemitic people I have ever met ever were Jewish themselves, sort of.
So, here we go. At least now they are finally admitting openly what they have believed all along.
