It’s more like the definition used by Right leaning government to cast Progressive social agendas as the downfall of society because in their case you slap “Neo” on something to mean “Untested and scary”. This isn’t so much a “Tankie” thing so much as a Fox News thing.

They get away with it because people aren’t taught or don’t absorb the actual technical meanings of different labels for subtypes of political philosophy. Hence why “liberal” has become buzz word to mean “civil rights and social emancipation enthusiasts”, “conservative” is abandoned to be this wishy-washy ground that evokes both a retaliatory resistance to social movements and/or a sort of nebulous (often false) vision of fiscal austerity and “communist” a brush to tar a variety of social movements with that handily has an implicit conspiracy aspect.

None of these definitions are accurate but they serve to muddy the water. That’s really the point of it. To rob us all of accurate ways to discuss political matters and to create team sport like voting blocks.
