Question

why do you think that caste rules are rigid?

Answer 1

caste rules were rigid. they did allow the untouchables to do any other jobs. they were not allowed to enter the area where located. untouchable families could not draw water from the village well or enter temples or schools. therefore, they were discriminated against and had no rights.

Answer 2

Caste system became rigid in India only whencaste and skin color were clubbed, or in other words, the Aryan Dravidian divide was brought upon.... Hence, the dwindling caste system was made rigid by those who wanted to eradicate it.
