Rangers Trust spokesman David Edgar has defended fellow fans while calling for action against those who smashed a window on the Villarreal team bus.
Rangers took a big support to Villarreal
"I would hope that, if these people are caught and identified, they are banned from Ibrox for life," he said.
"But we've been surprised by the almost glee with which sections of the media rushed this story out as if it was pillaging Viking hordes.
"But there were 18,000 fans there and only about 30 to 50 involved in this."
The window was broken as the Villarreal team bus travelled to the El Madrigal Stadium, while a group of Rangers fans later rocked the vehicle on its arrival.
However, there was little trouble during and after the Champions League match, which ended with Rangers losing on away goals after a 1-1 draw in Spain.
European governing body Uefa is set to investigate the incidents, with both clubs possibly facing a fine after poor ticketing arrangements allowed many Rangers fans into home sections of the ground.
But Edgar told BBC Sport: "As far as Uefa is concerned, they can start talking about bans when they stop such incidents in Turkey, where it's par for the course, or in Italy, where it's par for the course.
"It's a shocking incident, but only shocking in the context of Rangers fans who are unrivalled in their behaviour, both at home and abroad.
"The reason the thing calmed down was not down to baton-charging Spanish police but because Rangers fans stopped the idiots doing it from doing it.
"As for the person who did it, he is not wanted at Ibrox and, if anybody knows who did it, they should report it to the club."
Edgar was critical of arrangements made by the Spanish club and the local police.
"Villarreal had 5,000 unsold tickets and they should have looked into that," he said.
"They did not believe Rangers or our fans when they said there would be thousands upon thousands going over there.
"There is no massive away support culture in Spain and they don't understand the passion of the Rangers fans.
"I believe the Rangers fans should be commended for the tremendous effort and it's a shame that one idiot has spoiled it for everybody.
"People tell me that the local police were itching to use their batons.
"It was horrible for the Villarreal players to be subjected to what happened and I apologise on behalf of one drunken lout.
"But I was proud to be a Blue Nose on the night."
