Basically, where they claim all data and statistics from China that portrays China in a positive light are fake without any proof ex: China covid data, Yet use data and statistics from China if it can be used to portray China in a negative light ex: Zenz Xinjiang IUD birthrate drop. Is there a name for this, it sounds like a logical fallacy?
It’s partially atrocity propaganda (massively exaggerating legitimate criticism, and sometimes just lying without any basis in reality, and never mentioning anything positive). Not sure if there’s a term that perfectly encompasses all of this behaviour, though
