I don't believe it's possible to be neutral. The world is already moving in certain directions, and to be neutral, to be passive in a situation like that, is to collaborate with whatever is going on. And I, as a teacher, do not want to be a collaborator with whatever is happening in the world. I want myself, as a teacher, and I want you, as students, to intercede with whatever is happening in the world.
