It's that people make up the stories they want to.
I'm struck by the case of Elin Ersson who's in the news today because she refused to sit down on a flight because there was a 52 year old, who had his asylum application denied, being deported to Afghanistan.
Originally it seems that she had intended to stage her protest because a minor was being deported, but the authorities (who almost certainly got wind of the protest) switched him with another person. It would be surprising if she knew any details of his application to remain.
Stuck on the plane, having paid for a ticket, she finds her protest sabotaged, and instead, knowing nothing about the 52 year old, realises her folly and continues her protest anyway. The grounds for his deportation could be entirely different, but because "Afghanistan is hell", no-one seeking asylum in Sweden should apparently be deported.
So they all get bundled off the plane.
Now everyone is saying that this man has been saved, and that she's a hero. Because that's a nice, fluffy story.
No-one seems to realise that the guy she originally intended to save is probably already in Afghanistan, and the same is probably true for the guy she apparently 'saved' yesterday who was probably put on the next available flight.
It doesn't matter what the news reports. People just make their own versions up.
