> Whataboutism (also known as whataboutery) is a variant of the tu quoque logical fallacy that attempts to discredit an opponent's position by charging them with hypocrisy without directly refuting or disproving their argument

Like GP said, it derails discussions into talking about a different bad actor than the actual one committing the bad behavior, while (intentional or not) minimizing said behavior. In short, just because the bad behavior exists elsewhere does not justify doing the bad behavior, or makes it any less bad, and the act of pointing it out can be a poor attempt at distraction from culpability.
