commonly spoken language in India is not Hindi but Urdu, Indian people I interact with here in Canada speak Urdu not Hindi, bollywood makes Urdu movies with Urdu songs as Bollywood was stablished by muslims with majority Muslim actors, Muslim writers and singers. Listen you their pure Hindi channels and you wont understand anything.
reason Hindus came out with Hindi is because Urdu was a Muslim Language is still a Muslim Language...listen you any of your RSS and their supported leaders and see what language they speak.
