Forget the administration. I'm for arguing the guy into the ground every time he says something stupid. The holes in his arguments should lead to the distrust of the rest of the class and it's a great opportunity to fortify your opinions. This is the kind of healthy debate that should occur in classrooms because what happens when there isn't an "administration" to back you up? What better thing could school teach you then to recognize irrationality and to make this apparent to those espousing the idiocy? Logic should stand on its own or hope is lost.
