"Whataboutism" has become a tedious buzzword and is now pretty much a signal of offtopicness here.
The word does have some curious properties. Since it's nearly always used reflexively, it reproduces the phenomenon it criticizes. That makes it a word with anti-persuasive power, i.e. it refutes itself.
