Being invited by the university or a student group is a reasonable expectation for any one outside of the campus to come and speak or hold a rally.
Now, perhaps a group of Aggies will form a student group and hold a white nationalist rally on the campus.
However, I think that if such a student group were to be formed on the Texas A&M campus, that the Battalion or other news organization would publish the names of they students who filed the paperwork to form the organization.
That’s part of open records and that’s the First Amendment.
The First Amendment means you have the Right to Speak.
It does not give you the Right to an audience.
We are going to need another revolutionary war of sorts before this is wise. At the least, we should be prepared for a rumble.
