So you agree that they should fight to keep the school all-female. You agree that they're not doing anything wrong.
You simply disagree with views which they may or may not have held in regards to VMI.
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.
