Yes its human nature for 200 million DALITS (self-designation for a group of people traditionally regarded as low caste or untouchables (outcastes) to complain. 
so sad to hear that so sad.
The word “Dalit” comes from the Sanskrit language, and means “ground”, “suppressed”, “crushed”, or “broken to pieces”. It was first used by Jyotirao Phule in the nineteenth century, in the context of the oppression faced by the erstwhile “untouchable” castes of the twice-born Hindus.
In the context of traditional Hindu society, Dalit status has often been historically associated with occupations regarded as ritually impure, such as any involving butchering, removal of rubbish, removal of waste and leatherwork. Dalits work as manual labourers, cleaning latrines and sewers, and clearing away rubbish. Engaging in these activities was considered to be polluting to the individual, and this pollution was considered contagious. As a result, Dalits were commonly segregated, and banned from full participation in Hindu social life. For example, they could not enter a temple or a school, and were required to stay outside the village. Elaborate precautions were sometimes observed to prevent incidental contact between Dalits and other castes. Discrimination against Dalits still exists in rural areas in the private sphere, in everyday matters such as access to eating places, schools, temples and water sources. It has largely disappeared in urban areas and in the public sphere.
