They would need to have absorbed that information beforehand. Convincing them when every propaganda outlet is blasting "BITCOINERS CAUSED THIS!" will be completely impossible.

I completely agree that we should have sympathy for them - and people in bad situations in general - but we also need to understand that they may become dangerous to our property, freedom and possibly even lives, if things play out this way.

Some study tested what feelings people had toward two fictional tribes of characters, one peaceful and one aggressive, and after the story was told it was revealed that the names of the tribes had been "mixed up", and people saw the peaceful tribe (which they thought was the aggressive one until after the story ended) as much worse, and the aggressive one as less bad, than the control group, which was told the story with the names unchanged, did.

As usual with these things, I don't remember the details, but it shows that being first with a true narrative is much more impactful than trying to correct a false narrative after it is already told.
