Okay, so, ad hominem is the name of a logic fallacy where, instead of arguing about the topic, a person will attack the other person in the argument.
Ad hominem (Latin for "to the man" or "to the person"), short for argumentum ad hominem, is a fallacious argumentative strategy whereby genuine discussion of the topic at hand is avoided by instead attacking the character, motive, or other attribute of the person making the argument, or persons associated with the argument, rather than attacking the substance of the argument itself.
