term in logic

"An ad hominem (Latin for "to the man"), short for argumentum ad hominem, is an attempt to negate the truth of a claim by pointing out a negative characteristic or unrelated belief of the person supporting it.

Ad hominem reasoning is normally described as a logical fallacy, more precisely, an informal fallacy and an irrelevance."

Just a starter of course, I'm sure there's a more nearly perfect term

would it be correct to say that A's argument is a tautology?

It's a form of ad homimen fallacy called tu quoque.

It is not a tautology.

the word is ad hominem ...(not ad hominen)

Thanks for pointing out the typo, Ragman.

I hope I didn't confuse ummm.

the logical term for this is freedom being the truth since it is u cut off out of all logics facts and concept sources

u r crazy how dare u mean u criticizin someone existing at a first place to dare meaning more insolence by claiming that u r the reason of all logics chains of existence ends **** u
im really wondering wat are they waitin for up there

for the record to absolutely sayin always all, criticizin another is impossible objectively, and when objective is the only translation of else perspective then the idea of criticizin else is all to liars that are takin advantage of freedom in its absolute dimension where they are relative inn

in truth, seeing else is always being real with which show the truth and how any and all is relative too but then truth is not the reality since it is reality reason so it is the freedom out, what is out is happy of else existence freedom which also makes it real as true with truth

**** u endlessly till u get the punishment u deserve
