Wonder if Greenberg is Jewish? If he is how rich to be acting like a Brownshirt against a supporter of the first potus to have a Jewish family member.
He knows it's OK with campus powers and the California Universities and Governments for him to beat up ‘the Jew’...oops, I mean the ‘Trump supporter’...
So you're right, Zachary Greenberg's become a brownshirt. No group is 'victim' forever. Sometimes they flip to thug.
