Most people consider it rude because it has been passed down through the centuries as a rude sign. If you look carefully at the 'Bayeux Tapestry', depicting the demise of King Harold to the French, you can clearly see Harold sticking out his tongue to the approaching French forces. A little known fact is that Harold kept his tongue out through the whole battle, until one very annoyed frenchman thought "how dare he be so rude!" He then proceeded to shoot Harold in the eye with an arrow. After the deed was done he stuck out his tongue and said "Nah Nah Ni Nah Nah!" This is also where that little phrase came from.
