It seems to me, though, that this would eventually come up in conversation. Much of human discourse is centered around the concept of individuals' inner experiences.
The thought that someone who seems on the outside very similar to me could be completely missing the "inner experience of self" that I (think I) have certainly feels wrong-- it's deeply uncomfortable and rather frightening. Furthermore, espousing such an idea opens the door to those who would attempt to use it to discriminate (likely by applying existing bias with a flimsy illusion of accuracy).
This one doesn't have much use to me beyond tangential thought experiments. It can be cited to justify terrible things in the hands of bigots, and I suspect it's fairly easily invalidated for all practical purposes.
