Jossi 50 of Wiki seems to me to be unreferenced Whenever anyone states a clearly obvious uncontested fact in Wiki which is what about 50 of Wiki is unless someone can show the logical fallacy of the statement being presented as fact it is usually not removed due to lack of documentation For example if I write that the Dravidian culture of India is centered towards the Southern end of India I generally won t document it as it is already a well known fact amongst those who know about India Now if I were wrong about this in an article then perhaps someone would first point out specifically that they have heard that the Dravidian culture is centered in the North of India and could I please document my claim that it is centered in the South But simply to remove without even saying why that doesn t seem to me to comply with general Wiki practice Could you please tell me exactly which facts in the above section you are finding trouble with and why Thanks
