It's basically just a club meeting. He isn't teaching classes no matter how they and spin it. People attending his little meetings get no credit from the college for attending.
If people want to gather to him despite the well documented fact that he is a liar, I guess that's their choice.
If the University goes out of their way to keep him off of campus, some will see that as evidence that they persecuted him for expressing his views.
Like all conceited liberal liars, he thrives on attention. Ignore him. Interest in his little meetings will wane quickly when it fails to provoke a response.
Just ignore him.
Is he still doing his “Indian” shtick?
Some students are pretty slow learners.
