You have no fucking idea what that terms means. Whataboutism is when you say “Johnny stole a cookie” and I use whataboutism to say “But you killed the dog 3 years ago.” Whataboutism is not when you say “Johnny stole a cookie” and I say “But you invaded and occupied the bakery, killed the original owners, steal the ingredients to make your cookies, and issue predatory loans to hungry people so they can buy your cookies at price gouging prices.”
It is not whataboutism to call out hypocrisy. It takes a special form of brain rot to not see this.
