Tankies supposedly oppose capitalism, and they only support anarchism when it's in the West.
The term is derived from those who sided with the tanks when the USSR rolled into towns and later when the CCP sent the military on their own citizens during an event that resulted in millions of deaths across their nation. You know, "communists" but without any power in the hands of the workers.
Tankies are Russian and Chinese imperialists. They hate America for its imperialism, but love Russia and China for theirs. They're also very pro-genocide while simultaneously denying genocides.
AnCaps want a stateless society, but it is a misdirection to install neo-feudalism. For some reason they believe they'll be on top.
Nah some dipshits back Russian imperialism like their forefathers backed Soviet imperialism. Thus there are tankies who agree with Trump vis a vis Ukraine even if they disagree on when and whom it is ok to be racist towards.
