Having said that it's a fair point so I'll endeavour to use the correct words in future.
Having said all that I wrote Kraut, it will remain Kraut and I will continue to use it (though with a few Sons of Bitches in there). Why? Because it is iconic. it is what the Americans call the Germans as distinct from the Fritzy, Bosh and Hun of the Brits.
Whilst we're on thr topic of Krauts, I have a big issue with the word "Falshy". It sounds like an R&B singer. Plus falsch or falscher is german for "wrong, incorrect".
If you can't be bothered with umlauts and words with more than 15 letters in them then just use the acronym FJ - it's what the krauts did (I mean the sons-of-bitches).
I found tons of 2R leggings in the US the last time I was there, and brought home five pairs. Had I known, I'd have bought pairs for you guys as well
As for the correct terms; it can never hurt to improve the impression.
