Well, yes they do, in large numbers: 300,000+ Christians in Nagaland, 250,000+ Sikhs, 90,000+ Kashmiri Muslims, thousanmds of Christians and Muslims elsewhere in the country, and tens of thousands of Assamese, Bodos, Dalits ("Untouchables," the aboriginal people of South Asia), Manipuris, Tamils, and others.
In 1994, the U.S. State Department reported that India had paid over 41,000 cash bounties to police for killing Sikhs. One such bounty was paid for killing a three-year-old boy, who was subsequently labelled a "terrorist."
I don't take a world view. We have enough to worry about right here in America. We can't police the whole world.
How many Hindus have flown airplanes into our buildings?
How many Tamils have blown holes in our warships and killed our sailors?
How many Sikhs have blown up our embassies and killed our Marines?
You'd do good arguing for the UN.
