If you identify qualia as behavioral parts of our physical models, then are you also willing to discard the properties philosophers have associated with qualia, such as
Ineffable, as they can't be explained using just words or mathematical sentences
Private, as they are inaccessible to outside third-person observers
Intrinsic, as they are fundamental to the way we experience the world
If you are willing to discard these properties, then I suggest we stop using the world "qualia" since you have simply taken all the meaning away once you have identified them with things that actually exist. This is what I mean when I say that I am denying qualia.
It is analogous to someone who denies that souls exist by first conceding that we could identify certain physical configurations as examples of souls, but then explaining that this would be confusing to anyone who talks about souls in the traditional sense. Far better in my view to discard the idea altogether.
