Gorkhas have been living in the Darjeeling hills since the 1700s ... much before Dr Campbell and britishers arrived !!! U get your facts straight before u think on this. So when half educated people like you say that gorkhas go back to Nepal, it does not make sense. The situation is very simple ... the commie govt of Bengal holds the same equal racist view as yours ... hence all these problems !!! There is no smoke without fire !!!
