Pro Bangladeshi people can opt shaking hands with anti India elements and that's a security threat to India. As I told , it's the people of Indian subcontinent who have no habit of staying together but bowing down in front of invaders who come as friends and kicks you and me badly. And one region is alone responsible for the fall of whole subcontinent. This is the history of whole Indian subcontinent.
The ego, arrogance and jealousy from eachother has already divided the subcontinent not because it was not powerful and rich but because people here were stupid and are stupid. And have been exploited century after century just by few in strength.
