You jumped into a discussion that was not about your theory so he had

Your ignorance is showing .. it is closing velocity (as observed by the
observer relative to whom M' is moving at v). Please try to keep up ..
these ideas have been around for over a hundred years, you'd think you'd
have heard of this before.

I get around the c+v problem by realizing tying the emission point of
the light wave to a point in three dimensional space is incorrect. A
pebble is dropped into the pool on the train. If an Observer on the
embankment was unable to detect the moving water and was only able to
detect the wave in the water, he would conclude the wave originated
from where the center of the pool is when he detected the wave. Any
Observer in any frame of reference who detects the wave will all
conclude the wave originated from where the center of the pool is when
they detect the wave. And all Observers will conclude the wave
traveled at the same speed from the center of the pool, thus 'c' is
maintained for light.

And in this case, you don't know which will happen.

And, of course, it can be any of an infinite number of values because not
only do we not know which has the greater absolute motion, we do not know
the direction or value of absolute motion for M and M' either.

Your theory basically says we cannot possibly know the relative rates at
which any pair of clocks tick.

Its useless.

Liar .. he did not
