We need to concentrate on rural areas. The cities are infested with Hindus.

Punjab will in another 10-20 years time become a hindu majority . Sikhs will become a minority (already are if you count only turbaned ones) in the last place they're a majority in . The hard-won achievements of punjabi suba movement of 1966 will all be erased. 

Yet people are leaving in their droves..

Punjab is developing fast. Better roads, transport and hotels. The tourism industry is booming in India as well as Punjab. The Amritsar airport is greatly developed  compared to 2 decades ago. Many flights are choosing to fly from there.

One of the main criteria for entry into heaven or mukti is not specifically defined as non meat eating. I think Guru ji has made this rule specifically for kalyug where the quality of meat is on a decline and the cause of major illnesses.  All religions have some sort of similarity. At the end of the day survival on this planet is crutial if you are to earn your place in the darga. Vich duniya sev kamaiye ta dharge besan paiye.  Only Hinduism specifically says meat is to be avoided. However a person who is closer to God would not want to hurt or destroy another animal hence adding to their lekha. This is why a Sikh who is closer to God makes a personal choice to avoid meat.
