P.S.: it's only whataboutism if it's actually a false equivalence.
If it goes like this:
A: "You are doing something bad to X."
B: "You are doing something much worse to X."
... then if both claims are actually true, accusing B of whataboutism is a *worse* fallacy.

E.g. it's fine if certain countries point out atrocities committed by Russias, particularly if those countries are not doing such.
If it's the US, OTOH, the list of atrocities they are complicit in at any given time is about five to ten times the length - so the attack works.

Maybe if you don't want opponents to distract from criticism by accusing you of hypocrisy, you should try not being objectively worse than them?

(Yes, whataboutism *is* a fallacy - but politics is not a court trial, and you are just as much under evaluation as your opponent.)
