"Moon of Alabama" comes from a Bertolt Brecht poem, and Brecht was a Marxist, so I see it as a dog-whistle. In any case the right-left dichotomy doesn't have much meaning anymore, not when it comes to fact-based articles at least.
Fascist talk, no offense. That’s the stuff PatSocs use.
"Left" in the US means "liberal, democrat". I prefer "communist" and "Marxist" to "leftist". People consider Lenin and Stalin to be "right deviation" of communism and China is considered "right wing" by the "ultraleftists".
Right-left dichotomy has roots in the 19th century French parliament, where the socialists sat on the left side, while liberals and monarchists sat on the right. Now rather than the labels remaining descriptive, people have begun to use them as if they were prescriptive.
I started reading MoA when the recent conflict in Ukraine started, it was one of the few places not cheerleading for NATO. While many communist parties and outlets came out against Russia and engaged in "bothsideism" condemning Russia's "imperialism". It's easy to be against Ukraine now, when their Nazism and NATO's aim to sacrifice the Ukrainian working class to hurt Russia became apparent, but during the first year there was so much pro-UA fervor that even communists were afraid of saying anything against Ukraine or NATO out of fear of being labeled Russian agents.
Edit: To add, I'm pretty sure b considers himself on the socialist/"leftist" side of things.
