Apparently the university administration (outside of the president, I'd assume) isn't too upset with the players either. Won't be any schollies pulled:

"The department of athletics is aware of the declarations made tonight by many of our student-athletes. We all must come together with leaders from across our campus to tackle these challenging issues and we support our student-athletes right to do so."

If the coaches and university administration aren't upset with the players, there's no reason posters on a Mississippi State message board should be. Kudos to them for exercising their First Amendment rights.
