Right now, College rules stipulate that "membership in any any selective membership organization operating inside the college community is grounds for expulsion." The "powers that be" could not convince their lawyer to extend this language beyond the borders of campus, because such a broad assertion would affect many other students, staff, and faculty (Many of whom are members of fraternal organizations chartered elsewhere).
Essentially because of the impact of the civil rights legislation of 64 and 68 the college has to treat everyone the same under their rules. They could make the rules more specific to include just dekes, but so far they have maintained they would not do that in the name of equity. Plus, doing that would merely make them look more like the bad guy.... and campus opinion is clearly behind freedom of association on this issue, even among most faculty and staff.
