"Most of the 'bauns' in Nepal do not have a clue on what a real 'brahmin' is." Not that I am arguing in favor of a caste or another, but isn't this whole concept of caste a culture, something that is learned and passed on to the next generation? Doesn't it mean that there's no absolute point of reference? It is only perceivable that the understanding of a "a real brahmin" may vary from culture to culture. Your statement may be flawed.
