Some people here aren't getting it. Dartmouth has conservative groups on its campus that keep the Indian nickname alive, along with a conservative newspaper that promotes use of the old name. Therefore, whatever bad "conservative" factors exist on Dartmouth's campus must automatically exist on UND's campus.
That's what started the entire controversy. If Dartmouth had problems after changing its nickname, then UND must automatically have even greater problems because it's still using a "hostile and abusive" nickname. The activists believe that to end racism, all discussion of conservative ideals must be stamped out on college campuses. It's just another way to censor free expression.
