That's still the theory, except it's not politically correct to say it out loud. There was an idiot re-tweeted by the VP, who claimed "Buddha was Blonde with Blue-eyes; so was Pāṇinī". You might claim he's an idiot and "AMT is a sophisticated theory you pleb", but it actually is not. As we speak, Indologists like Bronkhorst, Beckwith and many others in EBT are scheming all sorts theories, which give wind to the old-Nazi ideas of "(early) Buddhism" being close to the early "Aryan religion", by claiming that the Shakyamuni was a remnant of original Steppe clans.

The way West frames/manipulates History (based on so little evidence) is deeply violent, and has roots in Xtianity and its violence. This is precisely the issue with this racial theory from the backdoor, and anyone with any shred of morality/ethics should stand with India, and for the indegeneity of its culture, civilization and languages.
