Its JI only who has dislike for Bengali language. Lot of JI supporters here make fun of Bengali language with their tuta-phoota knowlege of Urdu.
No one should make fun of any language as it's very disrespectful, but why do Indians love our language more than we do? I mean, they are "Indian first" after all then come ethnicities and religion. Whereas Bangladeshis are either Bengali or Bengali Muslim first (depending on the person, but that's a different story). Now I don't mean to be disrespectful, but this seems like a typical case of "Maar che maashir dorod"
I'm not a nationalist but Allah has made me Bengali and I love Bengali and speaking it. I also wholeheartedly believe that the helms of the Bengali language should be in the hands of the majority, Muslim Bengalis and/or Bangladeshis. But that's just my opinion.
Note: I also speak Urdu (to an intermediate level) and am not a Bihari. So I'm probably a raza-kaar.
The last time I asked an Indian girl whether she was Bengali or not, she replied "No, I'm Hindu" LOL
