I guess I react strongly because the comp theory is sometimes confused
with reductionist interpretation of it.

Not necessarily. Perhaps. It is more the error of explaining *away*, at
the level of the interpretation of some theory.

Ah, you say it! That is certainly a form of reductionism.

Honestly, I find the expression "neurophysiology is necessary and
sufficient for the mental states" rather ambiguous. It can be
reductionist (example are given in the writing of Patricia Churchland).
John Searle would say the same sentence in a much less reductionist
spirit, except that he has some reductionist notion of matter in the
background.

OK, but saying is not explaining. According to the explanation given,
we could decide if we are lead to a reductionist conception of the
mind/brain relation.

Saying that mental state does not exist is not just a reductionist
position, I think it is just wrong. Saying that mental states exist and
are "just" brain states is a form of reductionism.
It is hard to define "reductionism", but I would say it consists in
explaining away problems by imposing some univocal interpretation of a
theory. In "consciousness explained" Dennett explains *away* not only
consciousness but mainly matter. But his general view on consciousness
is not necessarily reductionist per se. Its notion of matter is very
reductionist, and from this follows a sort of reductionism in his
approach of the whole the mind-body question.
