Eccept that H can never correctly determine this of D, since if the H 
that is called by D does ever abort its simulation and returns 0, then D 
will halt, thus, since BY DEFINITION, the H we are talking about must be 
the same decider, unless you can show that a "Turing Equivalent Program" 
can act differently in two call sites, this can't happen.

You have been asked for this evidence, and failed to provide it, thus 
you have effectively admitted it is FALSE.

but (a) is never true for D

Execpt it doesn't, because H will always abort its simulation too soon, 
and an actual correct simulation will reach the return statement, 
showing H is incorrect.

Except it doesnt.

Right, and since the DEFINITION of Halting is about the ACTUAL BEHAVIOR 
of the machine, or equivalently the simulation of it by a ACTUAL UTM, 
you arguements about simution by the decider (which isn't a UTM) is just 
shwon to be a STRAWMAN, and your entire arguement a big fat LIE.

Nope, all YOUR arguement are strawman because you don't use the ACTUAL 
definiton of Halting.

Just a load of garbage, as proven.
