There's a person on CB telling us that being non-LDS in a majority LDS environment isn't always easy, and the response from some is "You're wrong, its actually fine."
I do believe that Retzlaff is probably avoiding most of the anti-Israel garbage that is happening on many campuses around the country and that BYU students are unlikely to be openly hostile to him being Jewish, which is a good thing. Doesn't mean that there aren't moments of insensitivity and ignorance that happens on the BYU campus.
