There a point that can be reached in a discussion where you realize that (assuming the other participant is honest, without which there are other insurmountable problems) you just don't have the requisite common understanding of reality to have a fruitful discussion.
The point at which you question the idea that belief, in general, isn't necessarily absolute is that point, for me, in this discussion.
Because belief isn't all-or-nothing.

Yes, it is exactly what I'm saying.
