He is not trying not to understand anywhere as strongly as you are.

Outside of WMytheology sets are either finite or not finite (infinite)
with no middle ground.

No such things exist in standard set theories.

Not at all. Actually infinite means set that is bigger than any single
FISON, such as the union of all FISIONS.
Note that if one can discriminate a FISON from a non_FISON, then one can
have a set of all FISONS, which is easily provable not to be the
surjective image of any FISON, and thus must be infinite.

Infiniteness of a set is not a number at all but a property possessed by
some sets, the property of being injectable to a proper subset of
itself, which property |N enjoys.
Does WM declare there is any natural number, n, such that n+1 is not
also a natural number? Unless WM can find some such natural number, the
the set of naturals injects into a proper subset of itself, and is thus
