Interesting read.
I am an Indian and I see Indian race as one. A colleague once looked up my hair (I have afro-like hair with looser curls, but in adundance) and asked me if I have mixed parentage. She said that all Indians have straight hair. She also went on to say that the fairer Indians are a result of European invasion in the past and that they are all in the north.
I am not sure what to say really...except for like what sapphire said - if you havent been to India you have no clue how mixed it is. You will find all shades of people all over the place. I have studied in 7 different schools in 7 different parts of India and have never categorised myself as a South Indian or a North Indian.
Honestly, when I am asked if I am a South Indian or North Indian, I just repeat - I am from India. Full stop.
Indian race is perhaps a result of a lot of different races which explians its diversity but it has so many traditions and culture which binds them all.
It is probably the ONLY race with so many hues and yet has so many similarities. The colour of hair for instance. As for hair being curly, wavy, straight or bald it is in all races with the exception of Chinese and African.
I wouldnt bog you down with the cultural and traditional similarities but the passion it shares for Cricket will wipe out any sort of categorisation! All Indians use their hands to eat their food. You will receive teh same sort of hospitality in any region. The list goes on....
Visit India! You will be amazed at its diversity and realise that it has much more than the just the spectrum of complexion of skin it has.
Pardon me if I diverted from the topic, (a little I am sure) but couldnt help it. Havent been home in a while - missing it I guess.
I by no means, represent anyone and each one of us have our own outlook and this was just mine.
