That is not true. That you call something "counter-factual" or "false"
or both does not mean that it is. Usually you don't do even that but
merely change the subject, apparently hoping that reders don't notice
that the rebuttal stays unprotested. A sufficient rebuttal is that
at least one of your claims remain unproven.

But the most important point is that you have not identified any
error in any proof of the uncomputability of halting.

You should consider identification of errors accurately enough
for correction as better than anything you may regard as an
insult but that is a matter of taste.
