The abusive ad hominem is not just a case of directing abusive language toward another person. . . . The fallacy is committed when one engages in a personal attack as a means of ignoring, discrediting, or blunting the force of another's argument.
"Although some faulty arguers may call attention to distasteful features of their opponents in order to manipulate the responses of their audience, most abusers apparently believe that such characteristics actually provide good reasons for ignoring or discrediting the arguments of those who have them. Logically, of course, the fact that any of these characteristics might fit an opponent provides no reason to ignore or discredit his or her arguments or criticisms."
(T. E. Damer, Attacking Faulty Reasoning. Wadsworth, 2001)
Your statement that 1 + 1 = 3 if you say it does is not confirmation bias at this stage because you already know this to be not the truth. This is called cognitive dissonance. That is two hold two opposing viewpoints in your mind conflictingly. Cognitive dissonance is an uncomfortable feeling caused by holding conflicting ideas simultaneously or you could also call it Orwellian "doublethink" named agfter the author George Orwell "1984, Animal Farm". Although different in nature but step back and looking they are perceptionally the same except in doublethink there is no conscious aversion to the idea or discomfort. You knowingly are believing both the lie and the truth comfortably.
Now that my friend is very dangerous.
