In terms of the written definition (and I am not even sure where that would come from considering it is a spectrum affected by a shifting overton window…), sure. But considering how much of online discourse is impacted by tankie influencers… meh

Its similar to (US) republicans where they have more or less become synonymous with the qanon crowd. That is not to say that they are all part of the qop, but they sure let them do the speaking for them.

Personally? I try to make it a point to use pejoratives like “tankies”. In part because I know people are stupid and will view even that as me saying “all leftists” (which is funny since, while I tend to identify more as a “liberal”, I am very much on that spectrum). But language evolves and a lot of the figureheads for (at least American, although I have seen some dumbfuck Europeans) Leftist movements tend to be blatant tankies and they don’t get the pushback because “they are increasing awareness”
