WI the fair-skinned blue-eyed ppl of northern India and Kashmir, who live in such places as the Hunza Valley (and whom are speculated also to be the descendants of Alexander the Great's hoplites), suddenly got the idea of becoming white supremacists at a point in time before the advent of the Hindu and Mughal Empires ? I read 1 account in a book by a journalist who'd covered the Kashmir conflict of meeting a tall blond blue-eyed man in the Hunza Valley who was initially assumed to be English or German due to his appearance, but spoke only the local language, and later encountering an entire village of such Nordic-looking villagers who could've been mistaken as coming straight off the plane from a major European city like Hamburg. WI the Nazis in their quest for 'racial purity' had managed to co-opt and indoctrinate these ppl with the white supremacist mindset ?
What about OTL aspects of white supremacy in the Indian subcontinent ? IIRC, didn't the Aryans move from northern India and expand militarily so that the darker-skinned Dravidians, who were perceived as inferiors, were driven further south ? And could you argue that the modern-day Hindu caste system is somewhat inherently racist, given the preference for lighter-skinned northern Indian Brahmins over the darker-skinned Dravidian lower castes, esp the 'Untouchables'/DALITS mainly from the south ? I also recall reading somewhere that the 'black demons' described in Hindu mythology are based on this struggle between the light-skinned Aryans whose religion evolved into Hinduism, and the pre-existing dark-skinned Dravidians, with the latter being represented as the servants of the dark. The British in their colonisation of the subcontinent also held such racist preconceptions of the various Indian ppls, in terms of their 'martial races' policy with their Brit Indian Army which prioritised the recruitment of lighter-skinned Gurkhas, Sikhs, and Punjabis who were considered as the best soldiering material while darker-skinned ppl such as the Bengalis were considered inferiors.
Also, re Iran, I remember reading somewhere that 1 19th C racial theorist, I think it may've been Gobineau, was initially obsessed with the idea of Iranians/Persians being the direct descendants of the original Aryans, but then being totally disappointed when he travelled there and found the local ppls wanting in terms of displaying any so-called 'Aryan' physical and other traits.
