For a start, it's nothing like what Richard said.Now that I cut out all of the weird formatting so we
can see what Richard actually said immediately below
what I said:

We can see that Richard misconstrued what I said.
That he construed: "Every D simulated by H"
to mean: {D never simulated by H} (his code example)
We can see that this seems to be too big of an error
to be an honest mistake.
If you want to disagree and say that it seems like an
honest mistake to you, that is OK.
If you try to get away with saying Richard made no mistake
everyone will know that you are lying.
I spent many hundreds out hours carefully formulating
those words that Richard intentionally twisted.

MIT Professor Michael Sipser agreed that these verbatim words are correct
(He has neither reviewed nor agreed to anything else in this paper)
"If simulating halt decider H correctly simulates its input D until H correctly determines that its simulated D would never stop running unless aborted then
H can abort its simulation of D and correctly report that D specifies a non-halting sequence of configurations."
