I dont agre with this bit, althouh most of what you say is true.
IF an Irish team qualifies, and are drawn against english or scottish opposition, the resulting confusion of who "*we" as a nation should support would be highlighted in the media.
While it wouldnt quite be the will *we/ wont *we situation of the current Lisbon Treaty shambles I think it would create a healthy debate about the sheep like behaviour of barstoolers versus the enlightened fans of the League of Ireland.
Lastly, of the 11,900 people who went to the Rovers -Real game, I would approximate that 5,00 were actively there to cheer on Rovers while the rest were interested onlookers. The efforts of the Rovers fans to creata a decent atmsophere as opposed to a library-esque exhibition game has resulted in some of these people subsequently going to Rovers games.
* This we is Irish people as a whole as opposed to LOI fans
