MN Grad Student "Investigated" For Classroom Dissension

As usual, FIRE is on the case. Most of it turned out well, but this caught my eye:

While it remains shameful that the student's views were so unpalatable to the professor that she ended up successfully excluding those views from her classroom, it is heartening that after just a few reminders about students' First Amendment rights, higher-level administrators finally did the right thing.

The student made statements that questioned the professor and the professor didn't like the statements, sought to have the student investigated for disrupting class and ultimately removed from the physical class.

I argue that it is not a good professor who cannot stand up to challenges and is actuall a disservice to all students by not allowing respectfully dissenting voices.
