A state of deep torment. Imagine being the descendant of thousands of years of toilet cleaners, despised by society, and treated as little better than walking turds. Imagine being all that and in a classroom with people whose ancestors were kings, merchant princes, and powerful priests and who until a century ago would have seen your mere presence an affront so deep that only the flogging of your entire family by another chamar would have sufficed. Imagine being all that and in a society that tells you are "equal" and that your English abilities make you "special" when you can clearly see the kshatriya and baniya kids getting girls who'd be disgusted by the sight of you, getting connections, getting jobs. Hell, the more "progressive" of these might even be fucking female chamars desperate to wipe the past by bearing one half-caste son. Of course deep cognitive dissonance follows.
Reservations have elevated some ST/SC families but this remains true.
