I think it has to do with complete distrust in western news and government (WNG). They can discount anything WNG says; especially when, it goes against their belief that the US is bad.
I believe we live in the most sophisticated propaganda machine ever developed but the folks who are a part of it mostly don’t lie. They’ve got the same problem the tankies have but reversed. The folks who work in WNG believe the US is good. They naturally distrust and minimize any info that would conflict with their beliefs.
There’s a lot of cognitive dissonance.
The only way I can navigate my belief in the fundamental inaccuracy of information is acknowledging it and accepting I don’t have enough info to be certain a lot of the time.
