Caste is, and always has bee, the bane of this accursed, god-forsaken, poverty-stricken land of filth and squalor. It's good that this NGO had mandated a caste-neutral environment prior to helping, but it sholdn't even be like that - people must take it upon themsleves, voluntarily, to break this curse of the evil caste system which ahs caused so much misery and oppression.
