Exactly. While certain dietary habits will most certainly have to shift if we’re to adequately tackle climate change, the framing of this as “everyone should just go vegan” falsely puts the onus on individual consumers to solve what is ultimately a systemic problem of production.
The thing that sets off alarm bells in my head for “Tankie but not communist” is someone who uncritically upholds Russia and/or Iran. Take, for instance, one Caleb Maupin. A guy who calls himself a Marxist, but hangs out with noted fascist Alexander Dugin, and was recently outed as a creepy sex pest.
