Whataboutism is when you try to dismiss someone's argument with "you didn't complain about X,Y,Z. this means you approve of X,Y,Z, this makes you hypocrite".
This is a logical fallacy because:
1. usually they did in fact complain about those other things. they are just not doing so in that specific conversation. Thus this is lying about their position.
2. they were not necessarily aware of it, therefore you can't say they approve
3. that isn't the topic of the conversation. so why would they start listing off everything bad that happened ever?
4. two wrongs don't make a right. You cannot dismiss someone pointing out that X is bad with pointing out Y is also bad.
However, in this case we did not have a whataboutism.
If someone goes around and makes the argument of
this statement clearly indicates that Russians are uniquely evil in a way that others are not. That the way Russians act is far worse than all the non-orcs (implied in this case to be the western nations).
Thus pointing out all those apparently forgotten examples of misdeeds by western countries is directly refuting the argument. It is not a whataboutism.
Here is an example of whataboutism:
actual whataboutism example said:
> Person A: I think what putin is doing is really bad
> Person B: you hypocrite. Am I the only one who forgot when USA did bad thing too?
> Person A: But I think those things were bad too. it was just not the topic we were discussing.
