Well, in and of itself a BRT is created to infringe on free speech. And, the key to free speech is to hear all sides and all opinions, allowing the listener to make their own judgement.

For instance the best way to get a Nazi to seem like a lunatic is to let the Nazi talk.

But in this case the University of Michigan BRT ironically overstepped the 1st Amendment and acted more deplorable than anyone they were silencing.

And we are so much more socially advanced to ever expect signs that read no black/whites/Asians...etc.

And the point of all this being that free speech is so important to our way of life, we will sue colleges that attempt to stop it.
