Dartmouth already has chapters of AKA, DST, Alpha Phi Alpha and Kappa Alpha Psi, plus Lambda Upsilon Lambda, which is a national Latino fraternity. They also have 5 co-ed fraternities, most of which I believe have houses. The options are there - it's just that according to Dartmouth's administration, they're not the "right" options. They want to have "theme houses" which to me is just as, if not more discriminatory than they are accusing Greeks of being. Their major gripe against the Greek system is that the students socialize the way they want to socialize, not the way the administration wants them to socialize.
Currently, there is a moratorium on ANY new Greek organizations, so if the male-female ratio is unbalanced or a multicultural org would like to expand there and cannot, it's firstly the administration's fault.

They have a history of the whole Greek system at the school. As it shows, the Dartmouth students took a stand against the nationals that still had "white clauses" in their bylaws, and disaffiliated if need be in protest. How many other Greek systems at the time could say that?
