My opinion of Ms. Mock has just dropped a few notches.
In my understanding, Hillel is a religious and social organization. The
change.org petition provides no evidence that Hillel does what they accuse it of, so it's impossible for me to evaluate it. The petition does contain some very dubious claims about Brown as a university, also unsubstantiated, so if that is the level of discourse I have strong doubts.
In my opinion, a flimsy justification for supporting this attack on Hillel.
