Whataboutism is a concept cooked up by a british columnist in order to dismiss IRA criticism of actions taken by the british army. It was then popularised by a zionist to dismiss palestinians.

Also, you're using it wrong. "Whataboutism" is not just "whenever someone mentions anyone doing anything" it is especially not "whataboutism" when someone gives context to actions and accusations.

CNN? The same CNN that is being blocked by the White House?

Yes. I think you are aware enough to understand how disingenuous your argument is.
