Please don't call them "the far left". They're just pretending, in reality they're authoritarians defending Russia, China and Iran, while shitting on the West at every opportunity.
Alt left covers way too many factions of people that it could apply to. You have disaffected liberals, anti-woke progressives, left-lib Joe Rogan types, tankies and MAGA communists. MAGAcoms are just tankies who vote for populist Republicans because Bolsheviks and Republicans happen to align on many/social cultural issues and support using the state to crack down on what they consider moral depravity.
