That's because people think there is some universal race of "Indians" that are the same, when it's probably the most diverse place on Earth. 4 major religions, 26 official languages and is the only place on Earth where all major "races" of humans have lived for thousands of years. Go to North India, you'll see lighter skinned people with green eyes, light brown hair, people who resemble Syrians, Iranians etc. Go East, you'll see more Asiatic features, tibetans, Mongolians, Thai, east-asian, go south, you'll see darker skin, more African features, similar appearances to Sri Lankans, Samoans, Fijians etc.
India is basically the result of a millenia of cultures mixing together etc. Very diverse. It's quite sad what happened to this guy. India is dealing with massive westernization and modernization while struggling with its traditional and conservative identity.
Four major ethno/linguistic groups in India. Dravidian, Indo-European, Austro-Asiatic and Tibeto-Burman
The picture is what some Indian genome initiative group sort of rudimentary described as the ethnic groups to get a sense. Now remember, that millenia of invasions, sharing, cross-cultural contact, it's become like a melting pot of such groups.
