I don't think a lawsuit will work or is necessarily the right tactic but I can understand feeling hoodwinked if the distinguishing feature of the institution I applied to and have been attending is changed midstream (and, yes, I know this happened at the Citadel and I feel sorry for the men it happened to, for the same reason. But a publicly funded institution is held to different governmental standards, rightly or wrongly.)
As I posted when another article on this subject was posted several weeks ago, I can understand the viewpoint of the women at Wells and I don't think their valid point of view should be mocked. They specifically applied to a women-only college because they wanted that experience. There are still several all-male colleges in existence also and I think there's a place for private single-sex colleges. Unfortunately, if the market can't support them they'll do what Wells is doing and nothing can stop it. But I understand the distress of people who are halfway through their education there. I think waiting 2 years or so and letting the current students graduate before implementing a drastic change like this would make more sense. Incoming students would know ahead of time what kind of school they are applying to.
The change will not take place for four years. Any young ladie currently enrolled will not have to share a classroom with stinky boys... That is why the lawsuit will fall apart
