A group formed to assert the right of Irish soccer fans to boo Glasgow Rangers players at Lansdowne Road is seeking a meeting with the FAI to discuss the issue.
Describing itself as a "non-sectarian, non-racist organisation", OK2BOO has also written to European soccer's governing body, UEFA, to "explain" the booing of current or former Rangers players at international games.
It emerged this week that UEFA has decided against sanctioning the FAI after investigating a complaint into the allegedly sectarian booing of Rangers star Shota Arveladze when Ireland played Georgia in June.
But the issue may arise again in next week's friendly with Australia, whose squad includes two Rangers players.
The FAI has promised to take action against any fans who target the Rangers players, including possible ejection from the ground.
Yesterday the man behind OK2BOO, Celtic fan Mr Enda Fanning, criticised the FAI's stance as "misguided".
Launching the group's website www.ok2boo.com, he admitted most of those involved in the initiative were also Celtic supporters.
He himself did not boo Rangers players at Lansdowne, he said, but he defended the right of others to engage in what was now "an integral part" of football, based on "rivalry, jealousy, or the desire to intimidate" opponents.
"It could reasonably be argued that such treatment is pointless, boorish or even counter-productive; however, it most certainly is not racist, bigoted or sectarian," he added.
He also criticised UEFA for mounting an investigation on the basis of a single complaint from a member of the public.
"Critically, there was nothing in the referee's or the UEFA observer's report about it.
"They got one letter from one guy. So who decided that, yeah, that's racism?"
Mr Fanning claimed the FAI had "painted itself into a corner" by accepting the sectarian premise, rather than arguing that the boos were inspired "purely by inter-club rivalry".
An FAI spokesman confirmed receipt of a letter from the group, and said it would meet representatives "if appropriate".
At a press conference this week, the FAI chief executive, Mr Fran Rooney, said that it was only when players were targeted on the basis of race or religious affiliation that booing was a problem.
"We're not saying you can't boo players. It's part of the game that you intimidate players and the referee.
"You want to create a cauldron of pressure."
