In one of your posts Rosina you made this observation:
....the UK has always had a welcoming attitude apart from a few lunatics of the sort that prompted the original post.
Now whilst I may have taken this phrase out of context, what I found difficult to accept was the word "always" - I think most of us are of an age when we remember the "No blacks, No Irish, No Dogs" notices in B&B and guest house windows.
That was the 1950s, when many of us were at school, and it also included the dreadful Notting Hill Race Riots, and whilst that era may have passed, the recent issues at Yorkshire Cricket Club does not seem to suggest that "always" welcoming is a UK characteristic.
The challenge for the UK seems to be that the unconscious antipathy to foreigners is particularly hard to pin down and education may well be a key.
But, judging by what appears to be an upsurge in recent years, we still have some way to go.
