India is a poor country while BD is land of Milk and Honey. BD Muslims are well fed, they are better in height, strength, fairness etc. Not that difficult to identify.
And the 400-500 million Indians living below the poverty line in Vasant Vihar in Delhi and have canals of honey and milk running through their houses.
Incidentally, for the Pakistanis who don't know what Vasant Vihar is - it is like the crowded localities of Samanabad Lahore and is thought to be one of the posh'est locality of Delhi.
