I’ve been fairly busy recently with work but I read a very good comment right now about semantics.
An Indo-European migration is a very different term to an “Aryan invasion”; the latter seems simply to be a Euro-colonialist divide & rule tactic.
I confess I don’t know much on the matter but I don’t see how the recent genetics somehow justifies anything more than a population movement.
Until there is more evidence of an “Aryan invasion”; I don’t see why such hurtful terms need to be bandied about (it only accentuates unnecessary divisions, which do have modern-Day political consequences).
We should be wary of external narratives foisted on a vulnerable Subcontinent; South Asians have a worrying propensity for ideology that has already cost so much in terms lives, prosperity & prestige..
