Well, I know. It’s just that it shows. America was a very different country then,and even nerdy science fiction writes were just naturally manly. The style used by Asimov (and plenty of others) is not from the world of Johnny Depp or Barack Obama.
For 1950s’ style of which you speak try some Heinlein, he was a naval academy graduate and could be a real red-neck when he wanted to be. “The Moon is a Harsh Mistress” an “Stranger in a Strange Land” are two of his best imop.
