Under Hinduism there are over 30,000 endogamous groups within India -- i.e. groups that will not breed or marry with each other for religious or ethnic reasons.
The Hindu caste-based notions of racial purity and Jim Crow in India make it an utter hellhole of segregation.
Christian missionaries have been preaching Christian universal love and equality in God' eyes to Indians for generations now.
High caste hindus (such as the Hindu engineers, shop owners, doctors and lawyers that are establishing themselves and their religio/cultural caste system in America) are fighting back in India, however -- fighting to the death against the Christians.
Although there are only a tiny fraction of poor Indians who are Christian, their insistence hat God loves us all equally and their rejection of segregation is a mortal threat to all Hindus and Hinduism.
For this they are routinely beaten to death and even immolated. See, for example, this article in the Independent:

I am aware that the mass murder of Christian peasants does not have the same appeal for the Slate readership as a spray-painted swastika or a tombstone pushed over, but I though I would pass this article on for those Christians who do read your website.
