Indeed, but not all whattaboutism are equal.
There's one to show hypocrisy. "You accuse A of doing this horrible thing, but what about this similar thing you do that is 10x worse".
There's one to deflect the blame. "You accuse me of doing this horrible thing, but what about that not so nice thing that is in no way related, relevant nor equivalent that you do?"
And there's the pointless pedantic one: "You say you care about B, but what about C, D, E?"
