Tathagataji, the problem is that the 'profession' got defined by birth and worst still since India did not had a concept of dignity of labor, certain professions got labelled as extremely lower category. People who were born into families practicing these professions were then forced to lead a life full of insults, humilition, fear, opression and torture. If they were talented in other areas (more cushy professions) then opportunities were stolen from them, unjustly, causing mental anguish, pain and emotional truma. Haven't you read about the story of Eklayva from Mahabharata. It's a shamelful event and Guru Drona must have been a first class racist who would have put Hitler to shame.
