Indian languages carry the legacy of caste [?]

This article here, claims so. I am ambivalent towards this, since they do not carry against only the lower caste. They do so against the upper castes too. And, a prejudice is not in the language, but the people who made the langauge. The language merely reflects this prejudice. English, due to its Judeo-Christian origin carries enough bias against anyone who is not a white, anglo-saxon. An example? The word Philistine. Check the meaning and its not-so-subtle reference to people who live in what is today referred to as Palestine!
