State propaganda is the de facto means by which tankies incorporate new information into theory: People may have their own "learning processes", but ones that contradict the large state either learn to conform better, stop being tankies, or get purged. Thus anyone who has been a tankie for more than a year "settles theory" in a way that is causally determined by state propaganda, i.e. they treat it as dogma.
This means they back the large state no matter what, and other states when the propaganda allows it. And indeed we see that tankies approve of large communist states attacking small ones or engaging in CIA-style political interference.
I am not asking you to adhere to communist texts more closely, I am asking you to see how the process by which you change your mind can causally be traced back to the owners of large Chinese corporations justifying the accumulation of capital.
