whataboutism, the rhetorical practice of responding to an accusation or difficult question by making a counteraccusation, by asking a different but related question, or by raising a different issue altogether.

Whataboutism often serves to reduce the perceived plausibility or seriousness of the original accusation or question by suggesting that the person advancing it is hypocritical or that the responder’s misbehavior is not unique or unprecedented.
