Whataboutism

This is from my website,

Whataboutery. People are called out on their "whataboutery" when they point out hypocrisy. For example, if a father tells his child not to smoke, and the child says "what about you? You smoke several packs a day!" The argument is that one shouldn't smoke, not that the one making the argument is exempt from that rule. So a "what about you" response does not address the argument, thus, is fallacious. However, it is a valid question that does warrant a response. Perhaps the father would respond "I am an idiot with no self-control." But if the father simply responded "that's 'whataboutery,'" it would be akin to the fallacy fallacy, where the implication is that because the response is a fallacy, then it must be incorrect, unreasonable, or undeserving of a response. This is a deflection and an argumentative cop out. Feel free to point out the whataboutery, but respond to the accusation and don't stop dialog because you have your opponent on a technicality.
