I was a child during the nineteen forties and my father, two brothers and three brothers in law all served in the British Army, one only lost his life. Despite their war time activities however they managed to portray an atmosphere of respect for all peoples including their 'enemies' (strained, in the case of the one who had been fighting the Japanese in Burma) This atmosphere rubbed off on me and during my own time doing National Service I too, respected the peoples in whose countries I served as a British Airman.
I was proud to be British and saw the Welsh, Scots and Northern Irish as natural friends and partners. Indeed during my subsequent career, during which I worked extensively in Wales and Scotland, I had no reason to doubt that my feelings of warmth and friendship were not mutually agreeable.
In recent years however, I perceive a nasty edge on the lips of some people towards others who they generalise as being antipathetic towards themselves, and I wonder if this has to do with their own need to feel themselves collective victims. After all, for those lacking in a sense of personal and collective purpose, to if they can see themselves as victims, this is, itself, justification for an absence of a more satisfactory and socially cohesive purpose.
I was fortunate to have been brought up in the family I was and so claim no credit for 'liking people.' (the odd spat is natural). However, it is hard to like someone who sets out to dislike and traduce you on the basis of your place of birth before they have even met you. Its a sort of racism without the colour angle.
As to my time in the USA Midwest. Wonderful. I never met anyone I didn't like. Because we lived in the sticks, one family even gave us a car for my wife to drive. A great people and I was as much at home there as I have been wherever I have lived.
