I still don't see how satire is supposed to detect anything other than who gets that it's satire, and who takes it at face value -- which is not even possible until you, uhhh, read or saw the satire. So that point of yours, it's lost on me unless you elaborate.
My premise is that people who fail to detect satire do so because their existing bias makes them see what they want to see. People apparently disable their critical thinking apparatus when presented with an argument that even superficially resembles their own viewpoint.
