How does caste hirarchy justifies whatever moron Ambumani is doing ?
Harvard and Stanford are in a country where people were enslaved , brought and sold like cattles till 18th century and had no right to education. These people had no political rights and crushed in name of colour till 1962. Still Harvard and stanford are based on merit.
OBC in India are not disadvantaged , In fact most of the today's OBC castes are the one who crushed SC and ST.
