    Amazing talk. From this other information tumbling out of Europe’s dirty past, looks like ’White man’s burden’ in reality meant ’the burden to appear superior at whatever cost’. One can only imagine the inferiority complex the early whites must have felt seeing the dark heathen natives’ superiority in trade, calculations, navigation, astronomy, architecture etc.!

    Ravi Chikkam

    I am extremely impressed with the depth and breadth of the knowledge. I am more educated in one hour than I had been [in] several years.

    Superb, thought provoking, eye opening!

    (Anon.) Dazhizhe

    Thank you for the interview, I enjoyed it a lot. I am so glad that somebody is on the project of digging into historical evidence and telling history as it is. I just hope that more people will join in the process so that our children will learn a history that more correctly reflects the evidence we have. Much of the primary source that Western historians rely on for ancient Greece dates back to around the Renaissance and after, which is more than 1000 years after the supposed fact. Any scrupulous historian would consider such sources to be highly questionable and unreliable.

    Prof. Raju congratulation for bringing the truth to light. Keep on telling the truth. There are special forces at work with special interest to try to prevent you from showing the truth. Truth buried for long will come to light, truth is stronger than falsehood.…You should be given the Nobel prize for all your work.
