From
https://en.wikipedia.org/wiki/Hand-waving:
"Hand-waving (with various spellings) is a pejorative label for
attempting to be seen as effective – in word, reasoning, or deed – while
actually doing nothing effective or substantial.[1] It is often applied
to debating techniques that involve fallacies, misdirection and the
glossing over of details.[2] It is also used academically to indicate
unproven claims and skipped steps in proofs (sometimes intentionally, as
in lectures and instructional materials), with some specific meanings in
particular fields, including literary criticism, speculative fiction,
mathematics, logic, science and engineering."

All the above blather about engines is a perfect example of arm waving.
Nothing you said has anything whatsoever to do with a "new" theory of
electromagnetics.
Nor have you said anything about how your "new theory" ion rocket would
be any different than conventional ion rockets.

Melt and bite are two entirely different things.
