You see to me this is where PC has gone mad. No wonder this country is in a mess, my old grandfather has the right to call them japs, he spent 18 months in a POW camp, starved, beaten and built their bridges, are you going to tell him its not PC to call his tormentors Japs?
You make a very good point. I've had a quick glance at the history books and it seems that across the centuries my family has been treated abominably by the Hun, the Eyetie, the Dagos, the Japs, the Chinks, the Gooks, Johnny Turk, various brands of Colonial and just about every other race or breed who wear funny clothes, eat funny food, look a bit shifty and frankly smell bad. And that's just the British half...
Your incisive post has lit in my head a bulb of such clarity and brilliance that all the dark nooks of ignorance and half-knowledge are swept away. I thank you for that and feel free now to call foreign types by their proper names and hold them in low contempt for what their ancestors did. Luckily, we Brits have been noble and kind from day one, so we have nothing to fear.
On the matter of WW2, my father's brother was killed in Hong Kong in 1941 (along with most of 1 Middx. Regt). His parents and his surviving siblings enjoyed the use of Japanese consumer goods and the company of Japanse friends in the decades that followed. The worst I ever had to suffer was being asked not to watch
Tora! Tora! Tora! while my grandparents were in the room. Similarly, my father was treated in a beastly way by Germans but we grew up post-war with many friends who had served in the Wehrmacht and some slightly dodgier military elements. History doesn't excuse offensive language where it is meant to offend.
