It's just a very 'Olde England' view of the provinces. We live in a multi-cultural, multi-racial, global village. Many of those moving work in a highly-skilled, high-tech, well-remunerated industry... and yet they appear to believe that civilisation stops at the borders of Blighty.
Anyway... English people don't get a hard time for supporting England up here... That's to be encouraged.. It's any Scots supporting them who get pelters!!
