Aren't you a part of that 'nascent professional class' minus the vices that you have mentioned?
This is the 2nd time I am seeing this line of argument, the 1st time I saw it in facebook where some 'intellectuals' were discussing that how the IIT/IIM guys and other such professionals are just well-trained, and nothing more than that. I didn't reply to them then following my childhood learning that "kana ke kana bolite nai, khora ke khora bolite nai", but I will tell you what I didn't tell them then...in the last paragraph.
While knowing far better math isn't a criterion for 'drawing the narrative', but the same is also true for skills like writing poetry or acting! Besides, what is an "Elite class" in a democratic political structure? In the real world the narratives are drawn by the hardcore politicians (and most of these politicians have a professional background, though I am not taking that line of argument).
I will tell you what internet and social media has done, these technologies have made information easily accessible to the public, so understandably sharper 'nascent professional class' quickly finds out the flaws or misinformation in the arguments of these self-proclaimed 'intellectuals', and using the social media publicly points it out! Leftists have made a ecosystem that supports and promotes only the people with leftist bent, and outcasts anyone voicing a different narrative, as described by the O'sullivan's First Law. Just see how the writers boycotted the Bangalore Lit Fest just because one of the founder members of that event voiced a different opinion! Now the internet and social media is threatening their cozy club of (leftist) 'intellectuals', hence the hue and cry.
For example, in a Netaji Subhash Chandra Bose related thread I posted an article by the historian Dr Purabi Roy, and landed in deep shit when a member here who was supporting Nehru busted that article! Dr Roy found a picture of Netaji from some archive and after duly scrutinizing it in her professional capacity concluded that the picture was probably taken in Russia after his disappearance, and went on to write a long elaborate piece on her discovery in a mainstream English newspaper. That pdf fellow just did a image search and in two seconds showed that the picture was taken in Germany during his stay there (something that I should have done without trusting the historian). Now imagine what degree of 'intolerance' Dr Roy would feel if someone tweets her with that google link or post it in her facebook profile!
Btw, if you are wondering why did I write "Understandably sharper nascent professional class" above; I am not sure about the rest of the world, but at least in India the bottom 40%-50% of the students go to study in arts stream, barring a very few exceptions, and the mediocre among that bottom 40%-50% go to study history, again barring a very few exceptions, later in life they might give each other the certificate of intellectuality, but more often than not they are not the most intelligent specimens of the population, it's just a feel-good tag that some people love to wear, in reality "Buddhijibi" is a bogus term.
