Jai Bhim is a cheerful greeting. Ten million Indians greet each other in this manner. They're the Dalits who are a proud community. They inherited an extremely difficult life. Their parents and grandparents and untold generations before them were outcasts in society. Even today they still encounter prejudice and experience helplessness.
For more than a millenium their ancestors lived as outcasts. People had a horror of touching them. Others even avoided being in their proximity as their shadow was considered polluting. If they went to school they were seated separately, If they were able to obtain work they did the dirtiest and lowest paid jobs.
