The people who don't care about the truth and the people who will point out fallacies all day are the same people. Shouting "Ad hominem!" and pointing your wand at the opponent is just another way to "own people with facts and logic" (read: counterfeit the form of a winning argument without the substance of it). That's why pointing out fallacies to win an argument is called the fallacy fallacy.
