I hate being that guy, but...

Y'all are using the term "ad hominem" wrong. It's not a stand in replacement for a smearjob, an attack on character or just a general insult.

Ad hominem is a logical fallacy where you attempt to invalidate your opponent's argument BECAUSE OF their character.

"You are an idiot and you are wrong." is not an ad hominem.

"You are an idiot and that is why you are wrong" is an ad hominem.

Thank you for listening to this public service announcement.
