If we are able to explain why you believe in, and talk about qualia without referring to qualia whatsoever in our explanation, then we should reject the existence of qualia as a hypothesis.

And I assume your claim is that we can explain why I believe in Qualia without referring to qualia?

I haven’t thought that hard about this and am open to that argument. But afaict your comments here so far haven’t actually addressed this question yet.

Edit: to be clear, I don't really much why other people talk about qualia. I care why I perceive myself to experience things. If it's an illusion, cool, but then why do I experience the illusion?
