Consciousness is a vague, folksy term, and science will provide a better definition as the explanation progresses

.
Descartes clearly defined it as that which thinks, the thinking thing. In a sense, you are correct that the turn is often used vaguely, but because matter is defined in a way that rejects it having secondary qualities, that means that secondary qualities exist in the mind, but if they exist in the mind, that means mind cant’t be matter entirely, because the mind has secondary qualities, and secondary qualities are not material.
This is just the reasoning of the early modern philosophers, the creators of the intellectual foundation you use. This is also why they tend to be dualists or idealists, and that materialism was taken to be rather blind.
Which it will, because humans are good at this stuff. The type of mind which worked out how to determine the exact elements in a distant star, just by looking at it with a prism, is not going to give up explaining itself after only a couple of decades research.
What I argued is that consciousness can’t be understood by science, because everything that couldn’t be understood by science was tossed into the pile of things we call “consciousness.” Consciousness just is those things that exist, yet can’t be measured by science, like secondary qualities (intentionality too). If you sweep all the dirt under the rug, it makes no sense to try and sweep the dirt already under the rug under the rug?
btw you linked that blog before. Another problem with it, and a strange mistake for a physics PhD to make, is he says “if man knows any truth at all, the redness of an apple is a reality that truly exists in the apple”. Nope. Illuminate it with blue light and the apple is black.
He wouldn’t deny that there is a subjective component to these things, just that it isn’t entirely subjective. Optical illusions regarding three dimensional cubes on two dimensional surfaces doesn’t make us doubt the objectivity of three dimensions.
Color not being subjective in its entirety is actually a good thing for the materialist, because it redefines what matter is so he isn’t stuck with the dualism I pointed out above.
