Thanks to Shivaji southern india was left untouched........

That is not true, not to denigrade The great Maratha leader, he was instrumental in preventing one form of chuvanism in what we call as Maharastra now. The imapct of islam is pretty minimal in south basically because of the very strong cultural identity in the south, be it the Tamil/telugu/kannada/malayalam land. Also thanks to many reasons like, relatively stable kingdoms in the south, the language disconnect between the north and south, vindhyas terrain, tiredness of the invaders etc.

Since we are talking of the invaders and the genocide in India, I am surprised by the non inclusion of the references about the genocide in Rig veda that were commited on the Indians by the invading vedics.
