I said bigotry is enshrined in the GAA because it is in the rules of the association that no club or county board is permitted to allow soccer/rugby on their grounds. I'd say 'foreign games' but the gah seem to be ok with american football, boxing, special olympics etc putting money into the coffers.
In Europe Galway played Groninigen at a communal sports ground in Carraroe that happened to also be used by the GAA. If it was a GAA ground they would not have been allowed. The GAA refused permission to use Pearse Park, incidentally. The Odense game in 91 was Ballaghdereen, which was a bit of an anomaly in that the ground wasn't registered with the GAA, so the club went ahead and rented it to GUFC. The GAA were not impressed.
Certainly the bigotry is weakening, partly from a new more pragmatic generation fighting a rearguard action against soccer, but it's still enshrined in the GAA constitution.
When was that charity game played as a matter of interest? Dundalk hosted more than one local GAA club for training on the 'plastic' pitch during the big freeze in 2010-11.
