There's another one of your contradictions. "Cancellation (of two waves)

an effect caused by itself. That won't fly.

:-) Sorry, Cecil. It's a fact.

It may be a truth, but only in your mind. It is certainly not a fact.

Cancellation requires at least two waves.

:-) Cancellation requires zero waves You can't have it both ways..

Cancellation can occur between zero waves? That's just bafflegab.
If zero waves exist, wave cancellation is impossible.

Maxwell's equations contain partial differentials
for dx, dy, dz, and dt.

Yes they do, and for any set of finite values of those variables for two
superposed functions of equal amplitude an opposite phase, the solution is
zero. You can write the functions for the two waves and prove they cannot
exist.

You are again confusing cause and effect. The solution is zero in only one
direction in a transmission line and we already know that. The principle of
conservation of energy dictates that the solution cannot be zero in the
opposite direction. The two rearward-traveling wavefronts cancel each other.
Their intrinsic energy components cannot be canceled. Therefore, that intrinsic
energy changes directions and joins the forward wave. It is all explained on
the Melles-Griot web page.

You seem incapable of conceiving of canceling wavefronts that exist for
only a dt of time.

Since the functions cancel during that dt of time as well as any other
length of time, you're right.

Your inability to conceptualize is your problem, not mine. My dog shares
that mental problem with you but I love her anyway.

I, OTOH, am completely incapable of conceiving of the cancellation
of two waves that never existed.

Not my problem.

Certainly not mine. Do you really expect any rational person to accept your
assertion that wave cancellation occurs between wavefronts that never existed?
Do you also believe that marriages occur between men and women who never existed?
