My sense is that many campus antidiscrimination rules (1) were originally aimed at discrimination by social organizations such as fraternities, sororities, and eating clubs, and that (2) their drafters didn't think much about how the rules might burden ideological groups' ability to disseminate their ideologies (for instance, if a "no religious discrimination by student groups" rule interferes with a religious group's ability to maintain its identity as a religious group). But I haven't been able to find much support for this assumption, which makes me wonder whether it's accurate.
Does anyone have any pointers to places that might either support or contradict my assumption? The more detail, of course, the better. If you'd be so kind, please limit comments to information about this factual issue, and not a discussion about whether such rules are a good idea. Thanks!
