Pointing out hypocrisy is not whataboutism. Whataboutism is when you bring up a separate topic as a criticism to distract from the original topic. For example, if you make fun of my cooking and I bring up your drawing skills in response, that’s whataboutism. If you suck at cooking and yet bring up me sucking at cooking, that’s just pointing fingers and trying to paint that as a negative for someone else when you possess the same deficiency.
