I've already changed the undersized boxes and removed most of the
nonlisted staples. I do have an attitude problem, and it gets worse the
more I think about it.

Then stop thinking about it. You can't win, you'll just get madder.

He was sarcastic and belittling. He said he would be there probably
about 10:00 and he didn't show up until noon. When he was looking at
the service panel in my basement, he disconnected a cable TV ground wire
that was in his way, and he didn't hook it back up again.

The ground may have been a mistake, and isn't a big deal. Approximate
times are just that, he showed up a few hours late. He has other
places to inspect, you don't. You could have called and canceled the
inspection if it was an issue to you.

He said the #6 neutral wire had to be marked white or gray or green from
end-to-end by the manufacturer. The code doesn't say that; I just
looked it up:
"310-12 (a) Grounded Conductors. Insulated conductors of No. 6 or
smaller, intended for use as grounded conductors of circuits, shall have
an outer identification of a white or natural gray color" [doesn't say
green, doesn't say continuous]

Article 310-12(b) is for equipment grounding conductors, and *it* says
the covering must have a continuous green covering or green stripe, and
it has an exception allowing the just the ends to be taped green "where
conditions of maintenance and supervision blah blah blah"

He's trying to apply parts of article 310-12b that don't really apply to
article 310-12a. 310-12a doesn't have an exception about taping the
ends white under "conditions of maintenance and supervision" because no
exception is necessary.

*All* code is as interpreted by the inspector and/or building
official.

Stop ****ing and moaning. Either fix the problems so you pass the
inspection or call the building official and ask for a grievance
hearing.
