A variation (related to Argument By Generalization) is to attack a whole class of people.For example, "Evolutionary biology is a sinister tool of the materialistic, atheistic religion of Secular Humanism." Similarly, one notorious waved away a whole category of evidence by announcing "All the scientists were drunk." Another variation is attack by innuendo: "Why don't scientists tell us what they really know; are they afraid of public panic ?Usually, the best way to cope with insults is to show mild amusement, and remain polite.A humorous comeback will probably work better than an angry one.

First, the arguer claims priority, but can he back up that claim ?It is related to Not Invented Here and Changing The Subject.Ad Hominem is not fallacious if the attack goes to the credibility of the argument.simply attempting to make the other person angry, without trying to address the argument at hand. Needling is also Ad Hominem if you insult your opponent.You may instead insult something the other person believes in ("Argumentum Ad Your Momium"), interrupt, clown to show disrespect, be noisy, fail to pass over the microphone, and numerous other tricks." Actually, pretty well any question has this effect to some extent.
