I predict not. I think the expelled students will either treat the expulsions as personal badges of honor or they will wonder how they could have gotten themselves into this position. Keep in mind that they will probably agree that the content of their "speech" was a bit gratuitous.
And if they make a stink, they could find themselves facing a lawsuit brought by the fraternity. The Greek system is big business and tarnishing the brand could bring grief down on them.
If you’re looking for another “bad guy” in this scenario- it would be SAE National. They cut these kids off in a split second. So much for brotherhood.
The number of precedents upholding freedom of speech, even racist speech, on public university campuses is significant.
And I mean really significant. See the link posted in the Volkhov piece cited earlier.
These kids are looking at having there personal and professional lives ruined. Deservedly so. They’ll (and perhaps more importantly their parents) be very receptive to the notion that they can recoup some of their expected financial losses from the unconstitutional expulsion. Which will be (probably already is) being made by a long line of lawyers and advocacy groups looking to represent them.
Which could very well include the ACLU. Which loves to take cases like this to demonstrate their “non-partisan” nature and commitment to the First Amendment.
