On a hot Tuesday afternoon, I walked into the recently reopened Dalit park in Noida, outside New Delhi. This is the park built by Mayawati, the 57-year-old former chief minister of Uttar Pradesh, as a memorial to the class of people long known in India as “untouchables.” A Dalit herself, Mayawati is a symbol of what traditionally oppressed classes and castes in India can do with their lives.
