Calling out whataboutism is perfectly acceptable when it is being used regardless of its origins.
It is in no way a logical fallacy and in fact the use of whataboutism is itself a logical fallacy.
The flaw in gorilladrum's argument is that the hypothetical example demonstrates the flaws in that specific situation and does not address problems in socialism as a whole yet they suggest it dismisses the ideology completely.
That's literally whataboutism, I criticized people using the vocabulary of "whataboutism" and then you said "but whatabout people who are doing whataboutism!"
To be clear, I dont believe whataboutism is a fallacy, but you do, so why are you doing it?
No it isn't. I am explaining why whataboutism is a fallacy itself. If you have a valid counterpoint to a claim there would be no need to engage with whataboutism.
I am not engaging in whataboutism but based on your view that it isn't fallacious Im not sure you will understand that. Not everyone is good at logical processing.
You're literally advocating for the concept of a fallacy which is basically whining "no you can't just provide context nooo that would defeat my point." Which was first used to excuse British colonial brutality and later used to defend lynching.
Whataboutism is an actual fallacy even if you din't recognize that.
If we were talking about the vast amounts of crimes the British East India company was responsible for and you chimed in with "whatabout the Dutch East India company's crimes" that would be a fallacious point because it is unrelated to the discussion and is only a diversionary tactic.
That is why whataboutism is a fallacy. It is used by people who cannot address the argument being made which you have done here.
The fact that the initial use of the term was to defray from atrocities doesn't make the use of whataboutisms logically valid.
If you mention that the soviet union used tear gas in rare instances and therefore they're authoritarian then I mention that the US frequently tear gasses protestors and BLM organizers keep showing up having shot themselves in the back of the head twice and you dont call them authoritarian that's "whataboutism" and it isnt a fallacy, it is providing context that points out hypocrisy.
You dont want to understand yourself to be a hypocrite but you don't want to change, is what it boils down to. So you do the though terminating "whataboutism" and you can ignore it.
