But the category error is that your decider and input just fail to be 
the needed programs.

The input because you insist it doesn't contain the code of the HHH that 
it calls, as that is some how a "variable" that can change based on who 
looks at it.

And the decider because it has two failings:

1) It doesn't process JUST the input, as programs in computability 
theory are required.

2) Your Decider HHH isn't a single program, which is why the input can't 
be one either.

THe fact that you just ignore this error, even when pointed out for 
years, just shows that you just don't care about telling lies, and you 
seem to be mentally incapable of learning the basics of the field you 
talk about.

Sorry, you *HAVE* sunk your reputation by the massive stupid lies you 
have told, and if you don't fix that, no one will ever trust anything 
you have written.
