Gorkhaland belongs to Gorkhas. And Gorkhas are integral part of india.
But Bengalese are not part of india now, as they have their own country called bangladesh. They have to leave india and settle in bangladesh or let us kick them out of india to bangladesh.
Merge Westbengal with Bihar, Orissa and assam. The whole region of west bengal will be indianised otherwise these crap bengalese will islamise with red communist flag.
