So Dalits are now diplomats?
Yes there are Dalits who are diplomats. The Indian constitution was written by one such dalit. The Indian PM is not even a brahmin, but a Sikh. They've even had a christian defense minister a few years ago, the current one is atheist. India has also had a muslim president... etc etc etc The political landscape in India is actually very very diverse.
“So Dalits are now diplomats?”
A dalit became president in 1997. And the largest Indian State is ruled by dalits. Diplomats are small potatoes.
