Re: that is an important point...

Good post. Yes, just because cultures and languages spread widely (and sometimes fiercely), has absolutely no bearing on racial interconnexion. It must be remembered that cultures and languages diffuse like wild fire as compared to population movements. Pan-Aryan theory is one of the longest drawn bows I've ever encountered. It is a redundant theory, but I do believe it's mentality is on the increase again under the neo-imperialism of the Anglo-American Empire.

Trying to equate language diffusion with a common racial link is about as ludicrously analogous as claiming that those who like Chinese cuisine must therefore have Chinese in them, every single individual in the USA must be racially derived from Great Britain because English is spoken everywhere, and the French and Poles suddenly one day all had German roots in them the very day Hitler invaded and changed all the street names into Gothic Deutsch. And half of Asia is suddenly and magically transformed into white bred middle Americans just because bible bashing evangelical missionaries and crusaders stationed on almost every hill top have converted them to the "American way".

Pan-Aryan theories were part of a pretext all of Imperialist design, employed by both the Nazis as well as the British Raj for assimilation purposes. But anyone of any reason will realise that there is about as much in common between a South Asian and an Englishman or German as there is between a Charger and a Pit Pony.
