Calling out your histrionics for what they are is not ad hominem. I’m attacking your statement, not your person.
Further, that’s not some sort of axiomatic law, that’s just a phrase. Even if it was, losers using ad hominem doesn’t mean winners don’t, that’s not how logic works.
Ad hominem: You're wrong because you're an idiot.
Just an insult: You're an idiot because you're wrong.
Furthermore, concluding that somebody is wrong because they used a logical fallacy is itself a logical fallacy. If I said "2+2=4 because you're an idiot" my reasoning would be fallacious, but to conclude that the answer must therefore not be four is also fallacious.
