If you learn the math the definition of AC and DC is totally irrelevant.
Your original Question #1 indicates that you don't know the math. That is
fine; it is something you can learn, but no amount of quibbling over
semantics is going to change the principles of circuits.

Forget the encyclopedia, learn differential equations instead. Encyclopedia
are for junior high school kids.

I will absolutely buy what you said, but understand the import of what
you're saying....you're saying that the language of "AC" and "DC" has
essentially been somewhat *******ized from its original meanings to
also mean zero-frequency and non-zero-frequency signals. Therefore, to
describe a 10Vpp signal with a 10VDC offset as an "AC" signal is
actually contrary to the original connation of "alternating current"
since it (net) results in a signal which yields only a mono-directional
(i.e. direct) current flow (albeit time variant). So in a sense, you
could say I am holding "pure" to the original (circa 1890's) definition
of AC/DC while its use has been "officially" corrupted to cover the
concepts of "zero frequency" and "non-zero-freuency".

Agree?
