Trump to sign order to interpret Judaism as a nationality--This won't fly

I do not think this will fly withstanding a court challenge as Trump wants to stop universities from allowing on their campuses boycott, divestment and sanction protests against Israel. He cannot limit political protests on universities it is a first amendment right and will only serve to ratchet up anti Israeli protests on universities and elsewhere.  If one is Russian can the state stop anti Russia sentiment on colleges, universities and elsewhere?

It is particularly egregious and the height of hypocrisy as Trump just gave a speech loaded with antisemitic sentiments. It was awful calling Jews real estate Jews who are horrible people but must vote for Trump as they have no choice. He is devoid of thoughtful analysis, does not read, and is ignorant. He probably will do this to recapture the Jewish vote he alienated during his speech also saying some Jews do not support Israel strongly enough. Who the hell is he to tell anyone who to support or how strongly to support it? There still is the freedom to advocate or not for political sentiment and policy in this country at least for the moment.
