Dalits worship a "demon" that in mythology was killed by the goddess
Durga. They believe he was a king that challenged the dominance of
the caste system. Jawaharlal Nehru University uses this feast day as
an occasion for political debates about caste, for which it
faces
prosecution for offending the religious feelings of higher caste
Indians that worship Durga.
I suppose they offend the religious feelings of Dalits, reciprocally,
but they won't be prosecuted for that.
Religious freedom means that people are free to hold any views in the
area of religion, and freedom of speech means they are free to
praise or condemn any religion.
