The mouth of Sauron has spoken

[Angrboda]

Perfect example of how US pop culture serves as indirect but effective propaganda against whomever the government wants you to hate at the moment.

Now Putin is not only New Modern Hitler but an evil wizard as well. It's cool that he's this all-powerful embodiment of evil in one sentence, and then an idiot doomed to fail in the next.

By identifying real-world politics with black-and-white fantasy fiction, we eliminate nuance, inconvenient facts, and the ability to think clearly.

You could apply that to your own thinking. By suggesting he's either masterful or a failure but not both, you're employing black and white thinking in order to posit a false dichotomy.
