I'm not so sure I would be so aggrieved.
If say a Polish lad born and bred in Ireland to Polish parents decided to decalre for Poland, I would have no qualms about that. As Irish people we should have a great understanding of emigration, diaspora, heritage and as a result I would always have empathy with any such decision.
Some of the Scottish club fans have taken it to a new level...basically its vile racism.
