AB - I would just like to say that the man who offered his stupid opinion to you was a rude oaf and should have minded his own business. It does in fact remind me of a family holiday years ago when we were driving through France and stopped off in Poitiers for lunch. We ordered our coffees, drinks and baguettes in our not fantastic French, but nevertheless made ourselves understood. Behind us in the queue were an English family who made no attempt to even try to speak French and ordered everything in English and then got snotty when the cafe owners looked put out. So yes you are always going to get people from dare I say it all four corners of Britain who do think the English language will take them anywhere and I agree it's possibly laziness or an arrogance. When I have visited Wales, I expect to hear people speaking Welsh and like anywhere else respect Wales and it's customs and it's desire to keep an old language alive by using it in tandem with English, or possibly exclusively. There will always be those that go to another country and behave badly but hopefully they don't represent all of us and I personally don't want to feel I have metomorphosized into Edward I when I visit Wales.
Speaking of bad behaviour, when I was first working up in London the Scots at times descend on our capital for football matches and they would rampage around London in a truly appalling manner, drunk, loud, abusive. Many, like myself were terrified when they came down and yes I know English fans don't cover themselves in glory either. Loutish behaviour is bad enough in the louts' own backyard, but worse when it's exported imo.
Turning to the St George flag controversy, there have been reported occasions, hopefully a few, but they hit the headlines, where people have been asked to not display our national flag or Union Jack for "fear" of upsetting others. I remember recently reading about plans to celebrate the Queens birthday and some councillor or other, can't remember where, asked "please can we not have Union Jack bunting" which of course was met with a backlash. These daft English people take it upon themselves to interpret the voice of non indigenous, who usually stand up and say that they do not have a problem with the national flag, Christmas or anything else that is inherently British and those that appoint themselves as arbitrators of what is acceptable as far as patriotic displays are concerned, unleash a hornet's nest of resentment. Anyone who has visited say France and America for example, will know that both these countries display their flags everywhere, and why not?
