And who is doing all the propaganda of Hindi being default language? Clearly not BJP. Dominating narrative is that centre government is shoving hindi down everyone's throat but situation is completely opposite.
I don't want to point out the names, but more often they come up with the statements like "Hindi is the national language and everyone should learn that" with the same tone they use for "India is for Hindus".
That said, if a person is earning his bread and butter in a non-native State then it kinda makes sense logically for him to learn the State's traditional language.
Whenever I visit Bangalore where most of the shop owners use Hindi equal to their local language which will surely agitate the language extremists and is not wrong though to communicate in the language they are comfortable but this gives the reason for the political party to play their games with their voters.
