There is ample genetic evidence of the Eastern European origin of the Indo-European peoples (as well as archeological, historical and linguistic evidence).
This is why it is still by far the most accepted theory in academia and it makes the most sense (wishes of Indian nationalists not-withstanding).
Also, just curiously... how do you get an Indian origin of the Indo-European people out of the link you posted? From the summary, it states nothing of the sort and merely confirms that there are genes in common between Europeans and some populations of India... a fact most everyone agrees on. More endogamy doesn't imply origin by any stretch.
So what's your point? My family origins are from UP and Punjab, with Pashtun and Central Asian forebears as well as some European and African admixture once they got to USA. I had my DNA sequenced, both ANI and ASI popped up as well as Central Asian. Does that mean I'm a living contradiction?
I do know what an abugida is, what are you driving at?

"Politicized theory". Not accepted by mainstream academics. Most likely not how it happened. Please don't confuse nationalistic pride with reality.
