It is not that they have a strange and eccentric viewpoint. It is that they are threatening to cause mischief, if the viewpoint of the institution, and most of its students continues to be respected--a form of blackmail, which should justify that expulsion.

Maybe. Student discipline at W&L is a little unusual. There are no disciplinary rules on campus regarding student behavior, except one rule which was installed, ironically, by Lee: that all students must behave as "gentlemen" (the undergrad side was still all-men up until 20 years ago or so, and the policy has never changed).
Anyway, the administration of the school holds no authority to discipline students. Instead, all discipline is vested in the students themselves. If a student believes another student has behaved in an ungentlemanly fashion, a committee is formed and the student is put on trial, during which time he is represented by counsel--often a law student. The trials are public and classes are cancelled so that the entire school may attend. Again ironically, the trials are held in Lee Chapel.
If he is found guilty, he is expelled. There is no other penalty. Most often, a student confronted with such a charge will withdraw from the University so as to avoid an expulsion on their permanent record.
