The child of the plane looked at everyone's reaction to his rant. He didn't get anything because they all had calm introspective expressions but he knows that not many agree with him. He knows why and he understands why they wouldn't agree with him. Their reluctance is because it is a lesson that he has learned.
They haven't learned that lesson because they haven't experienced what he experienced or seen what he saw. They didn't feel the rapid switches and near-perfect control of the champion of the furries. They haven't looked directly into those four eyes of the champion and felt him unravel their existence. They have no reason to fear that champion and wish to eliminate it.
Only he understands why he has decided not to underestimate the furries anymore. They don't because they haven't seen the relevance that he imbibed. He won't bother with them because they don't need to learn that lesson.
