The BSU had a reputation of being friendly to international students, and there were one or two Iranians on my floor. My roommate and I were able to freak them out a bit by posting notes to each other on our door written in runes. Yeah, paranoid.
They weren't as bad as they'd been on another campus, though, if testimony of a friend at the time may be believed. He told me that at that school the Iranian student marches had progressed to the point of harassing other students. (Sorry, I don't recall the institution.)
After a few weeks some Iranians made a serious strategic blunder, and harassed a black woman. Two nights later a number of cars came full of black men not seen before on campus, and the next day the Iranians were quiet as mice, and my friend said they remained so.
To every thing there is a season.
