 Any input that must be aborted to prevent the non
termination of HHH necessarily specifies non-halting
behavior or it would never need to be aborted.

 Everyone understands that DDD specifies a halting behaviour if HHH(DDD) does,

Any input that must be aborted to prevent the non
termination of HHH necessarily specifies non-halting
behavior or it would never need to be aborted.
 Disagreeing with the above is analogous to disagreeing
with arithmetic.

That the input is aborted does not mean that the input must be aborted.
And if the input specifies that its input is aborted then the behaviour
is not non-terminating.
