No because the scouts have St. George's day because of the English origins of the scouts.  So it's directly related to Englishness and in no way related to Aragon, Catalonia, Ethiopia, Georgia, Germany, Greece,Lithuania, Malta, Moldova, Montenegro, Portugal, Russia and Serbia.  They may also celebrate St. George's day, but for different reasons.  The Boy Scouts in America celebrate St. George's day EXCLUSIVELY due to their English origins.
