Spaniards insult the Catalans in NYC during the World Police & Fire Games

From August 26 to September 5, New York holds the 2011 World Police & Fire Games (WPFG),—the second largest multi-sport event in the world, surpassed only by the Summer Olympics—with the participation of police and firefighters teams from all over the world.
During one of the events, the Catalan team built a human castle—a Catalan tradition recently recognized as inmaterial world heritage—and raised the Catalan flag that symbolizes self-determination and independence, while the Spaniards in the event started shouting, whistling and insulting the Catalans, as seen in the following video.
This is not an isolated event. A couple of days ago, for instance, Cesc Fàbregas, player of F.C. Barcelona, celebrated the winning of the European Super Cup with the same type of flag. Some Spanish TVs made a big deal out of it and falsely said that the flag is not legal. In Twitter, the hashtag #CescMuerte (Cesc Death) became Trending Topic in Spain

Spanish flags only. All the rest forbidden.

The Football Spanish Royal Federation (RFEF) has forbidden all the flags which are not the Spanish one at the time of collecting an eventual trophy. From now the sportsmen of the combined state of football cannot carry any flag except the Spanish one.

Last July 31st the sub19 Spanish team won the European Football Cup. The Spanish coach, Ginés Meléndez snatched the Asturian flag to one of his players, just a kid. It was done in bad strength manners. After the controversy generated as for this coward action the RFEF has determined that from now are forbidden all the no Spanish flags. The federation only will tolerate "to the celebrations to the lawn or to the corresponding sportive terrain, but never during the delivery of the prize in case of victory." Meléndez has said that the kid “could not go up to the podium to collect the trophy with autonomic flags".

Some people opened a petition to consider Meléndez persona non grata (a not welcome person) in Asturies. Some Spaniards also think that the measure of the RFEF is that of a fascist state.
