@randahl "Whataboutism" is a bad name. In this context it means "changing the subject" or more colorfully "squirrel!"
When someone make a universal claim, and you point out a counterexample - the words "what about ..." are typically used. E.g.
Alice: All vans are white
Bob: What about that van over there? It looks blue to me.
Alice: I really hate whataboutery!
