Government agencies cannot discriminate. If the university decides that political expression and student activities are central enough to its mission to receive government grants, than it also must permit that expression to any group which is not contrary to that purpose.
However, Vanderbilt is a private university. It does not receive any direct payments from the government, except, of course, there may be certain programs which receive certain grants. Financial aid is paid to the student, to spend how they see fit within the parameters of the grant or loan; it’s no more “government-subsidized” than any grocery store which accepts food stamps.

Good point.
Like most large universities, Vandy receives tons of money in federal research grants for everything under the sun. They would be just another liberal-arts college without them.
