It is very nice to see you arguing for logical accuracy. I'm wondering if
you have been able to strengthen your own sense of logical accuracy.

The majority of us have certainly read the proof. But we did not all
understand it on first reading. At one point you argued:

as opposed to my:

You were very vehement that I was wrong.
Do you understand what the Halting Theorem (and Rice's Theorem) states now?

I am hoping that you have become able to recognize when you were wrong,
and learn from your mistakes.
