Nonsense. If somebody says "pick up that red object" we both know what is expected of us even though we may have very very different mental conceptions of the qualia "red" because we both agree that the dictionary says red is the color formed in the mind when light of a wavelength of 700 nanometers enters the eye, and that object is reflecting light that is doing precisely that to both of us.
But if the qualia of experiencing red is nothing more than the neuronal structure and process that consistently associates 700nm signals from the retina with the same actions as everyone else, e.g. saying "red", stopping at the light, eating the fruit,...then it seems to me it is perfectly justified to say people share the same qualia. That's the engineering stance. What the qualia/really /is, is a psuedo-problem, like what the wave-function of an electron really is. It's just the word for the fact that when you say, "Think of something red." I think of something reflecting 700mn photons.
