Definition of*ad hominem
1:*appealing to feelings or prejudices rather than intellect an*ad hominem*argument
2:*marked by or being an attack on an opponent's character rather than by an answer to the contentions made*made an*ad hominem*personal attack on his rival
Calling someone a moron is by definition a personal attack. It is simply the act of attacking the person rather than their statement or argument that makes it so. It has nothing to do with your knowledge of their personal life.
For example, If I called you a son of a bitch, that would be a personal attack regardless of my knowledge of your parentage.
The point is, one ought to focus on addressing the validity of a statement and not insulting the person making it.
Schneed for future reference, a more appropriate response may have been to say, "you posting this moronic unfounded piece of shit pisses me off."
I am available for further coaching at a modest hourly rate.
