Fun fact, my Grandpa fought in Europe, mostly Italy, during the War.

He once told me that you could tell where a man fought by what racial slurs they used. He didn't know that 'Nip' was a racial slur until the 1970s, because men in the European theater of war used 'Jap,' and when he'd heard 'Nip' he'd assumed it was a normal term, like 'Brit.'

That's interesting, as the 60's sitcom McHale's Navy does use "nip" and "nips", but I don't think they ever say "jap". It's set during W.W. II of course. It's been airing on one of the retro tv channels the past few years. I can't recall if Hogan's Heroes used "kraut" often.

I do recall an old tv Guide article about the 80's series Tales of The Gold Monkey, (set just before the war) where they were scrupulously avoiding using "Japs" in the scripts in spite of the setting. Derogatory terms for Nazis were okay, but characters couldn't use German in that context.

Funny how in TCW, clone troopers often call battle droids, "clankers" but apparently never utter slang terms for any of their flesh and blood opponents. ;)
