How High caste hindus treat low caste Dalits in India

Get over it!!
You have no idea what you are talking about and you have no businees talking about something which you have no idea of.
What you care is about how well you can put down hinduism and castism is a good way to beat it. I dont like questioning the motive of a poster but for you I have to. You wanted an egs of Muslim castism and I showed you how. I dont care what malicks are but the news do say how the dalit muslims feel that having an OBC malick muslims in the reservation quota eats into their share. Most caste violence in India now days start with similar problems.

Wow, world knows what Pakistan is famous for and we all know why does Pakistans name comes up so often in International news. Small matter of caste takes a back seat in your large country.

Its a form of castism. Does that exist in other places except the subcontinent.

Castism most likely developed out of tribal conflicts. Even now the lowest class in India are called Schedule tribes.
