The union flag is though our national flag. The reason players jump to the Republic in my eyes is more for the fact they have a better chance of playing in an international competition
It's your national flag and I respect that. You are British I have no wish to tell you otherwise. I'm Irish however - not just in my own crazy head, but legally under the Good Friday Agreement - I even hold a passport which says 'Irish Citizen'. That's the thing about NI, we have two nationalities living side by side and it will only ever work well if we both respect the other's right to their own nationality without trying to impose our own.
So my point was when it comes to supporting the national team of your birth it might be a bit easier if that team in some way represented my nationality. This is the reason Nationalists tend to support the Republic, because it's the only country that represents any aspect of our nationality.
I also understand that it won't be easy to change Windsor Park into a big 'neutral' Belfast Giants kind of gayosphere.
It'd be like asking the revellers on St Paddy's day in Belfast to tone down the Irishness so the Protestants can get involved (they actually tried to do this before). As much as it would be nice it's probably not going to happen.
