This is shadowboxing someone who doesn't exist. I know this is parody, but the ironic twist of saying Green Day was never or shouldn't be political...nobody was saying that.
Obviously people who like the thing they were protesting against will say something to the effect of "F this band who disagrees with me politically" or even "they shouldn't have been political in a NYE performance" but that is disagreeing with the content or timing of the message. There's nothing to parody there.
