@gopalgrg,you said it right.We as people of the 21st century should end these ill-practices.And we are going in the right direction though a lot is to be done.Its so culturally  engraved in  people and will take time but we ll one day come over it.Its even seen in gurung and magars(like the who is higher ranked between the 4 jaate and the 16 jaate gurungs) and other janajatis and not just the aryans.

Well solta,regarding buddhist culture being nepalese and hindu culture being indian,i dont know how much knowledge do u have abt buddhism but its just hinduism 2.0 and is a purely indian thought system based on hinduism.
If u regard buddhism nepali coz we pahadi people (including sherpas) follow a primitive form of pagan bon religion mixed with buddhism ,u ought to know it has been the religion of brahmins of north india for 1500+ years till the islamic invasion.And sages like Nagarjuna and bodhidharma have been critical to the development of mahayana tradition which was later brought to tibetan highlands through kashmir and ladakh and then came to nepal with the sherpas integrating stuffs and rituals of bon religion .The gurungs ,magars and tamangs recieved buddhism as late as 17th century with the tibetan influx in nepalese mountains.Thats when they gave up their pagan religion and took buddhism as their confession.
Hinduism was practiced by the people of awadh,tirahut and koch-bihar for thousands of years and hence too is our religion(but from ur opinion i get that u dont consider them nepalese).Even christianity is ours .But not the missionaries and jesuits.
