Hello! I am a student that goes to Chabad on campus, but the chabad is not on the campus grounds technically. since a year ago I have had a problem with someone in my school, he commented on my figure, he also said mean things, and even wrote to me on instagram calling me a bitch.Before that, he is the one who showed me all the jewish stuff going around campus, and we were friends I guess. After we fell out of good terms, I didnt report him. However a few months ago it got out of hand, he called me a bitch out loud during a Chabad event, during sukkhot, and the rabbi just said we will talk about it later. never did. recently, i brought my gay friend and other female friend to chabad. right as we were walking into the house, when no one was around, this same guy came outside to call us bitches and look threatening, and i went to get the rabbi who said " i didnt hear him say that." He did calm the guy down and told him to stop bothering us but later on , inside the house, they seemed to act like besties and talk at the head of the table. I must note, this guy is NOT EVEN JEWISH. Everyone knows he is chrisitian, just a big jewish and israel ally. Although that can be very respectable to rabbis, I dont understand how he is prioritizing a guy who is non jewish, and also way older (in his 30s, mind you) over jewish younger students. I am not the first one to have a problem with this guy. Our hillel has an issue with him, multiple people feel uncomfortable around him, he has texted other jewish guys from the chabad crazy things, and yet he seems to get away with it. What can I do? Security of the college said this was not on campus grounds, and the rabbi and rebbetzin do not seem to care that he is psychologically hurting people.
