What I mean is that using those categories does not much except
reinforcing stereotypes that are just artefacts of how things were learned
by certain groups of people, at the expense of not just everybody who
didn't learn it like that, but also everybody who doesn't want it to be
grouped like that.

both... well, if I understand the question.
I definitely can't pick one OR the other.
but then I cannot tell the difference between something "used as math" and
something "used as a filter".

I thought we were only talking about internal classes, not external (but a
good categorisation would expand naturally to externals)
no, if there were a dataflow category, it'd cover about 100% of the
classes, and then we'd need subcategories, and math could be a
subcategory, and it'd cover perhaps 90% of the classes, and then we'd need
a lot of subcategories because it's meaningless to have categories that
contain nearly 100% of the items; so instead we'd start from scratch with
i exposed some of those other ideas in the mail you replied to, but you
skipped over it then told me I'd want only a 3-category system that I
don't want either.

You're not a general user and neither I am. In a community as disparate as
pd, there may not be any such thing. But no matter what, there are always
people willing to claim themselves as more normal than others.

how do I do that?

is that the only thing that matters?

most people will choose to skip the question.

What's this kind of strawman...?
Stalin wore clothes, so, of course, decent people shouldn't. ;)
Really, I meant something more like: I could be removing category names
from my copy of 00.INTRO.txt... but I don't think I'd even bother with it.
In any case, category systems don't tend to affect my opinion of whatever
is put in the category.

BTW: if you look up the definition of "Filter" in Signal Theory, you find
out that "Filter" is a word used to refer to certain kind of Math
functions, that may remove or leave alone any given frequency, but will
never boost any frequency. This definition rules out [rpole~] from that
category, because the output of [rpole~] can be a bunch of dB above the
strength of the input signal.
