My interactions with that user have led me to believe that they’re less Marxist and more just pro-Xi. As Stalin demonstrated pretty clearly, there’s a difference between being the dictator of a nominally-communist country (or a fanboy of said dictator) and being an actual Marxist.
I feel like “noo it wasn’t a Nazi salute, or uh, it wasn’t intentional” is more of a “right of center” response instead of a “center” response, and “Elon Musk just did a Nazi salute on live TV” is closer to center, but otherwise this seems accurate.
Maybe the Overton window has shifted so far right that I’m wrong about that, though.
