Any other really stupid statements I can slap down for you?
insulting me until i agree with you is not a winning debate strategy.
Not trying to win a debate with you. If I was even remotely trying you would get well thought out responses (like the ones I posted to Skeleon). I'm just more than happy to continue to call you a tool. Don't want to be insulted? Don't start it next time...

Sorry about the above interjection. Someone else is trying to do your job for you and doing very poorly.
I notice this whole thread is tanking fast, with our debate being the most well thought out set of posts here. Are we even remotely on topic anymore? If not, good. This thread needs the bar raised. I will say
1) You are confabulating the underlying physical 'hardware' with the phenomenon of qualia. I'm not sure I can hold that against you given your stance.
2) I think we should keep this going, as it's been a hell of a good debate, and someone needs to keep some healthy discussion in here.
Ok, I'm abandoning our previous debate structure because it's getting unwieldy.
I know what you're talking about when you refer to fMRI, or at least I have a good concept. My Dad was a brilliant MD and I learned as much from him as I could. I suspect what you're getting at with this is the following: We can see the physical underpinnings of qualia by closely examining brain function. The two are not the same. However it would interesting to note that the process you describe works both ways. If I see red, you can see the "red" neurons light up in my head. If I imagine "red" you'd see the same thing. Essentially qualia and brain function affect each other.
The whole point behind discussing the EM spectrum beyond "visible light" and other species qualia of the EM spectrum is this: We can't (currently) quantify our qualia. If we look beyond just our own experience as humans the problem becomes significantly more challenging.
So here's what we're left with: We know that qualia arise from physical processes. We can not quantify qualia.
Your contention is that we will eventually be able to, based on a belief that all processes can (eventually) be quantified.
My contention is that we will never be able to quantify qualia because of the nature of qualia. I believe (eventually) someone will discover a proof as to why qualia can't be quantified and furthermore that proof will not rely on the supernatural or proof of a mind/body dualism. We will simply understand qualia well enough to say "of course they can't be quantified, that's how qualia work."
We can throw examples at each other all day but neither of us can truly prove our positions. So where do we go from here?
A few side notes:
Metaphysics is a branch of philosophy that deals with the nature of reality. It is not inherently a supernatural branch. To say you don't believe in metaphysics is like saying you don't believe reality has a nature. I think you're mixing metaphysics (philosophy) with metaphysics (layman's term for things outside of physics). If atheists, materialists and physicalists are right, then metaphysics simply is the same as physicalism.
"The Colour from Outer Space" is a short story by H.P. Lovecraft. In it an extraterrestrial object crashes into a farm. The object's color is one no human has ever seen before. It drives everyone who comes into contact with it insane, and just looking at it hurts in a deep mental and spiritual way.
Data to a computer is all 1's and 0's. We are capable of apprehending more than that. Computers are limited to a binary logic, humans can work with uncertainty and use a more complicated data set. Instead of simply on/off, we can handle on/off/both/neither. Given this, while the input may be in the form of 1's and 0's (which I suspect is not the case with all senses) the qualia formed from the input need not be.
So here's the question: How do we explore the nature of qualia qua qualia? (And this is where I hate philosophy speak. It leads to stupid sounding statements like qualia qua qualia) To translate: qua, the thing in itself, apart from the processes that give rise to it. How do we explore the nature of qualia without relying on neuroscience, so as to know that we are dealing with qualia and not the physical precursor processes?
