When I read about conversions till now, I always thought it justifiable that people should escape from the caste system into caste-free religions like Christianity or Islam. It has become clear that that was a delusion. Over the last few weeks or so people have been writing in to The Hindu's Letters to the editor section, listing the mechanisms by which caste is perpetuated, with great eagerness. Separate streets, separate burial grounds, separate seating at church, separate car festivals, no inter-marriages, no inter-dining even. Having read nothing about how muslim dalits fare in terms of discrimination, one does not know if the situation is similar there. But this is depressing enough.
