> worship "India's language is Hindi",

I think , what he is trying to say is, ascribing a single language to a diversified nation like India is not a good idea.

> Why do you believe that north indian language and religion are nonsense?

Free speech.LoL.I am not saying OP is right or is following HN etiquette, but that it is OP's opinion(not fact, not truth).

> I don't think North Indians are backward relative to South Indians. Although they are relatively poor.

Bihar is the most uneducated state in the country. Kolkata is a terrible to place to conduct business of any kind. Although , this is not representative of the North.

But what is North anyway ? Should we consider anything above Madhya Pradesh North ? Does Gujarat count as North ? Does Mizoram count as North ?
