They have created scriptures which are full of hatred, abuses and indignity against the lowest social order, i. e, dalits or untouchables. Those scriptures are sacred to them and the victims of those scriptures are to regard as sacred by them too. Else they are pilloried publicly or dragged into courts for hurting their sentiments and faith, which are undefinable, nebulous dependent on whimsical interpretation of the powerful sections of Hindu upper castes. They created caste and therefore they tend to support it for their benefit and to detriment of others below the ladder. For them caste is goldmine.
