Out of 39 states 20 prefer interacting in Hindi..even when they all have different mother tongue. Its just the minority south states prefer speaking in there languages which doesn't matter to other as no migrates there( non existent)

You understand that this is not regionally uniform, yes? The 40% Hindi speakers is not "40% Hindi speakers in any given region"; it is "40% Hindi speakers overall", where most of the Hindi speakers live in the northern states and various cities.

> i have seen situations where people find it easy to grasp hindi than any other languages

Again, this is highly regionally biased.

“Let’s speak Tamil or kannad. These states are doing supremely better than all of the Hindi speaking states. Obviously language has something to do with our success, and it would be wrong of us to keep it to ourselves when it should be used to help the nation.”

This short circuits enough wires, and is polite enough to not engage the depressing flame war that is sweeping such discussion.

It’s not logical, but most of this argument is not logical, the proof of which is too much for the margins of this comment.
