Wait. It was Wikipedia. Not even a dictionary.
"Tankie is a pejorative label generally applied to authoritarian communists, especially those who support or defend acts of repression by such regimes, their allies, or deny the occurrence of the events thereof."
So, as a pejorative the support or defense of Acts of Repression is so in the opinion of the person using the pejorative. It doesnt say who is being repessed, I want some stuff repressed. This is a piss poor definition because it's far from definite.
