Academic Freedom in the Classroom

It's an organizational tool to defend academic freedom in the classroom against intrusion by nosy administrators ora interfering other colleagues. The more free lance opinions they indulge in from their powerful position in front of the blackboard, the more they're putting more ad more of their students various degrees of antagonistic vulnerability. It does look like that, but what the professor says goes is only an approximation of what we're looking for. In the class room, that's not intra mirra. That's within the walls of space.
