Were the VMI and Citadel students not just as offended as these women are the the integration of their school? I recall a lot of grumbling from the male students at these institutions at the time. Not all of course, just as not all of the women at this college are protesting the change here.
One of the big differences between the cases of VMI and the Citadel and this school that people seem to be missing is that in this case the college is voluntarily admitting the opposite sex. The Citadel and VMI were forced into it by a lawsuit. The second major difference is that both of those schools are, AFAIK, supported by public money, unlike this school.
There is no excuse for a school that takes taxpayer money to discriminate. By that same token, however; a school may discriminate if it is a private institution. Would any critics of this school's students argue that Jerry Falwell's Liberty University, or the Boy Scouts of America, or Catholic seminaries be forced to accept atheists or openly gay persons? I think not.
Are private organizations not allowed to discriminate? Of course public pressure can be used to try to change opinions and thereby effect change, but laws?
Unfortunately, the distinction between the rights of private organizations and the obligations of organizations that accept public money are often overlooked by people trying to make a point.
