Unfortunately, delving into the personal side of the poster in order to win the arguments against him/her seems to be a behavioral mudus operandi of Ashu. I have seen this occur in past when he got into verbal fisticuffs with other posters too - Nepe, Paschim, Biswo and many others. Don't get me wrong. For the most part, I like what Ashu writes. His arguments, though you may agree or disagree with, are usually cogent. I even dare to say that I admire his writing style... to some degree. Though, I do get turned off by his usual false modesty and self-promotions that come out now and then. Ashu, Here's the thing, how on earth do you know about Rahul-vai's academic history? And say what you know is correct, even then, why in the world are you washing his so-called dirty laundry here? That is shameless!!
