Stop spreading the BS...there are lots of tribes in NA with non Nepali mother tounge. There are tharus, rajbansis, tamang,  rai, and gurungs in NA. The only people that were discriminated were and Tarai basi with Indian origin and the brahmins

Bramins  were probably steriotyped as a weak and cunning element...and Yadavs, Jhas and Guptas were probably steriotyped for being Indians.

Do not confuse the original Terai basi like Tharus, Dhimal, Rajbansis, and muslims with the new indian immigrants like Yadav, gupta, and Jhas

Editing it; Apparently b.a.h.u.n is a cuss word now in sajha..lol.
