I've played extensively in Europe and mostly to young people and I have never encountered anything like the behaviour I've seen from some youngsters over here.
One problem is the puritanical attitude to alcohol in the UK. Drinking is much more a part of social and family life in Europe and youngsters learn how to drink sensibly.
Another problem is that many Europeans seem to know who they are and feel a sense of belonging to there societies. In the UK Thatcher and other forces have been pushing the "no such thing as society" message and many now believe they are independent of any social unit bigger than their immediate family and friends. Where I live a lot of people define themselves by what they are not (sheep shagging Welsh, Haggis eating Scots, Cheese eating surrender Monkey French, and a lot more offensive racial stereotypes).
The UK is mostly ghettoised into NIMBY semidetached suburbia and badly designed Council sink Estates terrorized by a minority.
Trying to keep optimistic in modern Britain is difficult but this is my land and I'm proud to be from this beautiful and Ancient Island that has contributed so much to world culture in the past and may do again.
