I dont know about the superiority and inferiority but I do believe t hat the caste system is a major problem that exists in the people of today (and yesterday). I dont know why it makes you any different just because you were born in a different family. If a child born in a bahun family is reared in a shudra or whatever family what will the kid be? How will he be any different? I mean come on.. these are all crap. Just because u have certain genes doesnt make u any different. Culture and family values might differ.. but the fact remains that all are humans! I wonder when will we be able to look past all these dumb things.
