@JohnnyQB How does your reply have anything to do with the topic of discussion? Mentally ill, could one sign be that a person is ill-capable to stay on topic of a discussion? Would it be considered "right or wrong" to change the subject and attack a person rather than to address the information of the discussion?

Ad hominem (Latin for "to the person" ), short for argumentum ad hominem, is a term that is applied to several different types of arguments, most of which are fallacious. Typically it refers to 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. wikipedia

@JohnnyQB Or, are you just giving an example of how it is to be immoral by showing an example of a "wrong" thing to do by committing the sin of ad hominem fallacy?

@JohnnyQB Sin is a violation of Logic. Sin is to be immoral. Committing fallacy is a sin.
