America comes with both rights and responsibilities. You have, for example, the right to free speech, but you have the responsibility to not yell 'fire' in a crowded theater. If you don't live up to that responsibility, you face certain consequences. It's a simple but effective formula. Unfortunately, tenured professors are completely insulated from it. They can scream fire in their classrooms all they want - and then hide behind their tenure if anyone questions them on it.
