The Gun Culture in USA

B S Prakash writes about the prevalent concept which seems to be that "guns are a right and a necessity" in the US. If the the majority of the Americans are right, why is the overwhelmingly much larger majority outside of the US wrong about the need to bear arms ? {Interestingly : If "Democracy" means that decision of the majority of the people is to be observed, then surely USA is an anachronism within the world's citizenry ?}
