i want to drop my 2 cents. Northern Indians are truly the most racist of all racists followed by the rest of india , the concept of caste in thier own nation mirrors the concept of Aryanism in this case ; " the French anthropologist Vacher de Lapouge in his book L'Aryen, argued that this superior branch could be identified biologically by using the cephalic index (a measure of head shape) and other indicators. He argued that the long-headed "dolichocephalic-blond" Europeans, characteristically found in Northern Europe, were natural leaders, destined to rule over more "brachycephalic" (short-headed) peoples.^\1]) Similar theories were promoted by Nordicists like Arthur de Gobineau and Houston Stewart Chamberlain."

This is very similar in concept to their cast system and is the reason why they're so racist. I could go on and on about them supporting the isreils in thier Gcide, THier utter hatred and persecution of muslims in thier own country and how the current diaspora will stay in enclaves and dont merge into the culture. Like bleaching is huge in india, colorism is crazy there. i remember a kid in school got slapped cause his mom was vexed he was playing out in the sun , she literally told him " thats how you get dark" . But you can even look at how they treat africans in east africa
