Is it me, or is nothing straight forward? Let’s take your points one at a time.

“No light escapes from a black hole horizon because the gravitational red shift stretches the wave length so that it can't get out.”
Does this imply that the wavelength would have to be infinite in order to escape? If so, could it not escape when it became "effectively infinite"?

“…that time for the wave, in the reference frame of the light wave, is slowed down to 0, in comparison with clocks in our reference frame.”
Elsewhere, we met the argument that light could not be said to have a frame of reference. How could one re-phrase your statement in order to avoid ascribing a F of R to light?

“The original conception of the black hole was that the escape velocity for a black hole is greater than the speed of light”
Initially, this interpretation seemed to present no problems, but, light must always be measured as travelling at c, so it must be seen (or presumed, if there is no-one to see it) to be approaching the event horizon, from the inside, at c. What stops it from going through?

There never was nothing.
