Dave and Cindy are participating in a debate on the topic of censoring violence in movies on TV and in video games. Cindy has been assigned to argue that violence should be censored. At this part of the debate, Cindy is finishing her speech and Dave is starting his cross examination.

Cindy: "To summarize my points, it is clear that violence in various media, such as film and video games, has a statistically significant impact on peoples' patterns of behavior. As the twelve studies I cited indicated, this hypothesis is extremely well established. Since the state is obligated to protect its citizens from harm, it is clear that the government must act to censor such content in media. Well, I'm ready for your questions, Dave."
Dave: "Now, is it true that you play Ninja Mortal Death Master Combat II on a regular basis?"
Cindy: "Yes."
Dave: "Is that not one of the most violent video games? Did it not receive the coveted five bloody skulls award in Video Carnage Monthly?"
Cindy "Yes."
Dave: "Is it not true that you regularly watch and enjoy violent films, such as Dead Time, NightWatch, and Maximum Overkill?"
Cindy: "Yes."
Dave: "Is it also not true that you, in this very classroom, opposed censorship of violence in movies and such."
Cindy: "That is true."
Dave: "I need to go no further in my questions. Cindy has admitted that she has, by her very actions and words, opposed the censorship of violence. She plays violent games and watches violent movies. Thus, it can be clearly concluded that her claim that violence must be censored is clearly false."Red HerringPersonal AttackCircumstantial Ad HominemAd Hominem Tu QuoqueRed Herring: This is a wrong answer. Dave is not attempting to lead Cindy off the topic (censorship) with a red herring.Personal Attack: This is a wrong answer. While Dave is attacking Cindy, the attack is not one that is launched against her personal characteristics.Circumstantial Ad Hominem: This is a wrong answer. Dave is not attempting to attack Cindy's claim by asserting that she is making it simply out of self interest.Ad Hominem Tu Quoque: This is the right answer. Dave is asserting that Cindy's claim is false because it is inconsistent with what she has said in the past and it is inconsistent with her actions.Dave is clearly attacking Cindy, but what sort of attack is it?4
