No, because MLs aren’t necessarily tankies. And I do consider tankies a subset of Communists. Just not the very bright subset.
“Tankie” means someone who’s more interested in following a communist team rather then a communist ideal. Even if the team leader is just a grifter.
If you acknowledge the short comings of certain states that don’t really follow the “from each according to his ability to each according to his need”, you’re not a tankie.
