"Tankieism is Calvinism" sure is a thing that a person put down on a whiteboard. I've never seen an "anti-tankie" that wasn't some WASP type, but sure, being pro USSR and anti US is somehow magically pro-Calvinism. It really feels like that CHUD thing where they get called something as an insult (i.e. Calvinist) but don't understand it and just go "no u".
