The point there is not that the USA is bad but that it is order of magnitudes worse, which means that opposing its enemies must be considered through the lens of "Does this help the US?"
To say nothing of the incredible amount of State Department propaganda that many western so-called leftists readily accept at the same time as "disavowing" the US as "also bad". If you believe the same things about the US's enemies that the US is actively campaigning to make you believe, that is a red flag.
