Dear Dr. Yousefi,
1. Sorry, I don't want to think too deeply. To do so would become a disease making one chase after all the bygone era philosophers. Seems to me you enjoy and in it often!
2. Indeed I meant Dulama as in no need for Persian language to aim standing taller than itself.
3. The division of a well-established language into several pieces within connected geographical political domains is nothing short of political phenomena. To be specific, late Daud Khan and his cronies for lack of better words became too Persianized. And to overcome his ego, officially changed it to Dari. While from Qandahar to Ghazni, from Bomyan to Maimana and from Nangarhar to Badakhshan every one calls the language Farsi/Pharso. It is extremely rude to tell others what to call their mother language
