The California State University is following Vanderbilt and Michigan, banning Christian groups from campus. As in previous cases, the pretext is that they do not admit “all comers” if they require leaders to be Christian.
Of course, all campus groups choose leaders who ascribe to the group’s beliefs. (Just try to get elected president of the College Republicans/Democrats if you’re a Democrat/Republican.) Christian groups are being penalized for being forthright about it.
