> India's religion is the Aryan worshipping flavour of Hinduism
This seems very short sighted.
From an objective historical standpoint, the current Hinduism is no more 'Aryan' than it's 'Dravidian' or 'Indigineous'.
The Rig Vedic dieties which share origins with Nordic, Greek or other Indo European mythology are not the central point of the Hinduism since the middle ages. The present rituals and systems evolved over, 3000+ years, shaped by various political forces, most of which was never documented and we will never know.
The "North Indian == Aryan" was wording used in Tamil Nadu politics that's why people in comments are assuming your from there.
Your point is correct that current Nationalist side of politics is pushing some views in order to unify their voter base. (I don't want to talk about politics on a nerd forum.)
The only thing more "Aryan" about Hindu nationalism is they want to claim this historically baseless OIT theory (as if anything that comes from outside is impure and bad).
[to non indians reading this, the word Aryan refers to slightly different meaning than held in the west, while we are talking about same indo european bronze age peoples, both theories (Nazism or Periyar's Dravidianism), are pseudoscience shit.
