It is you who hasn't done enough research. What is visible to bare eyes cannot be seen by you blind people. Simply because you do not belong here. You came unclad and unfed running from centra asia. We gave you food and shelter. Instead of being thankful to us you colonised us and tortured us. If you want evidence, look into the shameless aryan works which go in the name of literature, ancient literature at that. That tells you what your shameless forefathers did to Indians.
