So, finally someone in Congress(I) learned to say the word 'sychophancy'! I wonder why it took them so long when the whole country has been witnessing this phenomenon for god knows how long.
I came across this interesting article by one Dr. Santosh Helekar, who seems to conclude that the Aryan invasion theory may be valid, after all! More importantly, there is the implication that the casteist tendencies might have had a racist origin - more specifically, Indo-European.
History is a tricky subject in India. History is somewhat politicized, in my opinion - which is sad, because history with an agenda goes against the tradition of holding 'Truth' to be paramount. It is better to be unsure and exploring than to be 'sure' and wrong.
