It's not just brahmins who indulge in using the term "Bhote". Magars, Rais, Gurungs, all do the same thing against Sherpas and Tibetans. What I have been told is that the term "Bhote" is reserved for Tibetans and Sherpas only. I have met some bahuns who use the term "bhote" liberally to describe Magars, Rais, Gurungs, etc, as well but most of these people use it disparagingly to put down people. I used to live in an apartment, in proximity of which lived other Nepali families. One family was Magar, while the other was "bhote". So people from the Magar family would come to me and made disparaging remarks about the "bhote" family. I personally believe all humans are created equal, so when I hear racist/ethnocentric/bigoted statements, I literally cringe. I was extremely uncomfortable when I was made to listen to these remarks, but what am I supposed to do?
