Nobody came to India from outside. We are all from Harappan civilization.

I just went over the comments. Apparently as per genetic tracking it shows that Aryans definitely came into India 100 generations ago, and that 100 generations is a long enough time that pretty much all Indian populations have some Aryan DNA. Yet, somehow, there are groups of Indians who will claim that the Aryans were invaders and you don't count as Indian even if you have been here for 100 generations.

I don't know of any other country on the planet where you could have been staying there for 100 generations, have your genes spread out across the entire population, and still be considered outsiders who destroyed the land.
