All I can say about that Dalit you met is that the person is really opportunistic.......a typical example of human version of chameleon .... Is it rational to be opportunistic? YES. Is it moral to be opportunistic? NO. To add more, how sensible is it to ask a person showing an apple, "Is it Black or Blue?" And how sensible is it to ask a person, "Who are more moral, upper casts or lower casts?" I just read an article few weeks ago in New York Times. It was about the increased admission rate of Asian in University of California at Berkely. Asian students amounts to 40% of total student body in the university. This particular university is one of those handful of universities in USA which bases its enrollment policy on the basis of academic qualification. The result beckons one and only truth - what would be the face of highly educated population in US had there been equal admission opportunity policy in US universities. Laamo kura laai chotkarimaa bhannu parda, if you think upper castes became upper caste because of their ability, then what do you have to say about white people who think of themselves as the uppermost race in the world?
