To insult a historian is free, to say that these statements are not backed up by reliable sources that is a very big mistake. The limits of Patagonia and the ones of Chile and Argentina have been very well documented by Carlos Morla Vicuña and Perito Moreno, in 1880. Frederic Lacroix in his "History of Patagonia " in 1841 defines all the limits, also Raul Rey Balmaceda in "Geografia Historica de la Patagonia " in 1976 confirms the limit of Northern Patagonia which are stated by me. The same is true to the historian Enrique Campos Menendez in his work " El alma de la Patagonia" based on a careful study done at the Archivo General de Indias in Seville, he states clearly the limits in year 2002. Also from a point of view of its Flora and Fauna, look at Hans Steffen. So, you have many different ways to reliably understand the same argument, both political, geographical, nature, human and cultural. To try to change the history and geographical references in year 2010 its a joke. If you are stating the above with good reference, I will be happy to continue with this matter, uderwise it would be considered an offence made without any support and a waste of your time and mine.
