Racial purity???

"The only people who should play for England are English people" - so says Jack Wilshere, who does in fact play (football) for England.  Oh, weren't things so much simpler back in the days when you were almost certainly born where your parents lived - and probably you grandparents too.  Can you remember when, to be eligible to play cricket for Yorkshire, you had to be born in Yorkshire (though it has to be said that a blind eye was occasionally turned)?  But then people started travelling - so what of an English couple who happen to be abroad when their child is born - is that child English? Common sense would say yes, but take it a step further - suppose that child continues to live and grow up abroad, and marries someone of a similar background, and they have a child.  We have decided that both are English, being born of English parents - though never having set foot here, so what of their child? English??  You see how complicated it gets.  So I think Wilshere has his heart in the right place, but needs to define exactly what he means by "English people".
