You view realism as a form of cruelty?
“The original post was from a person remembering a long way back in time to events that happened when he was a young man…Memories fade and get a bit obscure.”
So? I’ve remembered things incorrectly too, and there have been occasions when other people have helped me to identify and root out those errors, and I’ve been grateful for their assistance. Are you thinking that Mr. Osborn is now too feeble-minded and emotionally-frail to have any of his errors pointed out? Is it really a kindness to regard and treat him as something less than a fully competent adult?
For what it’s worth, I’m pretty sure nothing I said here will have any impact on him. And I think that because it never has. He trots this story out every chance he can–and uses it to push his agenda against nuclear technology that has nothing to do with nuclear bombs-and I’ve pointed out the nonsense in it on multiple occasions before. He tried to argue against it on one occasion that I can recall, and that did not go well, so now he just repeats the same story over and over as if nothing in it has ever been refuted or debunked. That isn’t faded memory. That’s intellectual dishonesty of the same kind we see in science deniers from the other end of the political spectrum.
“Also what was known scientifically back then probably bears no resemblance to what we know today.”
Nothing I pointed out that was wrong with the story involved anything that was not well-understood back then. The arguments that used geometry and atmospheric optics would have been understood centuries before then.
