I don't consider myself a tankie, because I'm an anarcho-syndicalist.
I've been called a tankie for suggesting that workers should organize tenant unions to kill the apartment bidding wars in NYC. I've been called a tankie for pointing out that their image of a tankie needs to almost have power to be any kind of threat worth warning against, and there are no tankies anywhere near power with the global rise of fascism. I've been called a tankie for asking someone to clarify what they meant by tankie. I've been told that scientific socialism both is and is not tankie behavior. The term is utterly meaningless. I've come to the conclusion that it's part of a 3rd red scare in an effort to sow division amongst the anticapitalist left.
