Also didn't you have sarcastic Chornobyl jokes in the 80s if you lived anywhere near East or Central Europe? We certainly did have a lot of them in East Germany.
It is not being presented as a tall tale or a sarcastic joke. It's being presented as fact. I'm merely asking why people feel the need to make up stories and to propagate stories that are untrue. That is a question I am genuinely interested in.
Why, when we know this is complete BS, do people feel the need to 1) make it up in the first place and 2) propagate the story without engaging their mental faculties.
People propagate falsehoods for numerous reasons. The first is, they don't know it's false. They hear a joke or a hypothetical story and repeat it as fact, and in the retelling it gets amplified. Details get conflated; someone hears a story about slightly radioactive cows and also about computers being affected by radiation, and blends them. Or an expat tells a story about his homeland, exaggerated slightly for effect, and is misunderstood by those who hear it based on their own biases.
In the end we only have so much brainpower. We don't always consider the plausibility of everything to a deep degree. I am nearly positive that you have propagated falsehood where you "should have known better."
And sometimes we tell things that are just a good story. I propagate the neural network tank recognition one to my students because it's a perfect story. I do say that I know it's probably false, but I'm sure some of them will repeat it to others as fact.
So that is your reason there.
I'm just interested in the undercurrent of why people seem to like this story and I think it pretty much is "Communism Bad" even though as mentioned otherwhere in this thread (and by me) capitalism has an awful record when it comes to food quality the one thing that is being knocked in this story.
