Many Hindus,as a friend noted,have a tendency to confuse the sthūla with the sūkṣma even in matters of directions of narrative weaving and geopolitics when it comes to narratives of our history,and the core reasons behind them. A particular example is the tendency to freak out on any suggestion that Aryans migrated to India(never mind that the seeing of the mantras of the śruti occurred all within the Indian subcontinent,which no one can deny). Of course,the (understandable) reason for the uneasiness with this is that it is used as a stick to beat Hindus with,calling them murderous Nazis,invaders,racial bigots(or some form of that) from the very beginning of their existence(or theses that extend in that direction). Most of them do not notice that even if OIT was proved beyond any doubt,the direction of the narratives purveyed by mlecchas and those who imbibe their ideologies would not change one bit at all. They will still continue to either blame brahmins or the entire society. Two examples in case would be DD Kosambi,who(along,or despite,or because of his belief in the fact that Indo-Iranians came from outside),noted about the genesis of brahmins
It seems that Kosambi was a little uncertain about the origin of the brahmanas, but he firmly and consistently held that they originally belonged to non-Aryan cultures and were very probably drawn from the Indus valley priests.
None of this prevented him from calling the intellectual production of āstika brahmins and everyone else like that of a mistletoe,which was beautiful but parasitic.
Or Hegel,who held an Out of India theory,but whose descriptions of Hindu philosophy are a manual on how to misinterpret and misunderstand Indian philosophy.
What needs to be needed is a properly oriented narrative,regardless of whether it is established that the descendants of Indo-Iranians/Indo-Aryans populated India or the Indian subcontinent was the Urheimat of the Indo-Europeans.
