Looking at the world like that is like plugging your ears and yelling "I can't hear you" whenever something goes against your preconceived narrative.
For example, when China announces they have landed on the far side of the moon, how exactly does their totalitarian governance impact the accuracy of this press brief? Is it not more beneficial for your own sake to pass on judgment (or at least defer on your judgment) based on the particular event over what their goverment is like?
It isn't as if I'm ignoring what they put out. We're not in total jingoistic denial of reality territory here :)
Regarding China's moon landing, their being a totalitarian government with a propagandistic focus matters a great deal. A lot of bad science has been foisted upon the world by similar regimes - look up Lamarckian inheritance in the USSR for instance if you haven't heard of it.
In this case though, we've got pictures, we know the rocket launched, etc, etc.
So, I'll sing praises to China when they do something praiseworthy, but by god I'm not trusting a statistic or a press brief coming out of that place, and no-one else with half a brain should either.
