We need this Aryan Dravidian crap - it's main use is to have a dig at Guys living up North. Even if its true - and Hindusim is a mixture of Drvaidian, Indus valley Civilization and Aryan vedic- does it matter now.
All that matter is that we are all Hindus.
And at the same time we have the bonus of winding each other up with this dravidian Aryan stuff , take the piss but in a fun way- and nobody get upset or physically harm - then keep this Aryan dravidian stuff going.
By the way- kanadigas are cheap SW copies of Tamils - this has been proven scientifically. :-)
