Whataboutism is not every time someone says “what about X”. It’s when you are asked a question and you dodge it by saying “What about X”. e.g.

“Lead is bad for health”, “sugar is bad for health”, “marijuana is bad for health”. Not whataboutism.

“Mr Senator what’s with your taxpayer funded holiday?”, “What about YOUR broken election promises?”. Whataboutism.

> “Whataboutism or whataboutery is a variant of the tu quoque logical fallacy, which attempts to discredit an opponent's position by charging hypocrisy without directly refuting or disproving the argument” - https://en.wikipedia.org/wiki/Whataboutism

Here I thought the word "whataboutism" could not be possibly be more overused. You realize that drawing parallels in a discussion is not whataboutism?
