If he wants to teach his students that grades "poison our educational environment", why is the solution to give everyone an A+? He's just using grades as currency to buy his students' support for his experiment in anarchy. I wonder how many of them would have still participated in his class if he had announced on the first day that everyone would get a C, a D, or an F?
