I am reluctant to engage with this, but... Sigh...
I have to ask... How do you explain the Anatolian languages?
Or what seems like a very clear progression: Sintashta -> Andronovo -> BMAC -> Indo-Aryan.
A long history in the subcontinent that predates BMAC does not imply linguistic continuity.
There's such an overwhelming set of evidence linguistic and materially... there's a reason why, yes, it's just Hindu nationalists/fundamentalists parroting this position.
