Bringing it back around to WONDER WOMAN (to stay on topic), this is how period pieces are inauthentic. They will give some of the flavour of the language at that time, but not the full monty. Because we couldn't take it. People would be demonstrating in the streets, if the characters in the movies talked the way that people really talked in those days. As it was, the generals in WONDER WOMAN said some harsh things but nowhere near what they would have said in the real world.
