Why is castism and untouchability stil rampant in South India?
Even with much higher GDP per capita and literacy rate (except Andhra) than west Bengal, why is castism and untouchability stil rampant in South India than west bengal (except Kerala).
I often hear from Tamils that they don't use the surname and instead use their father's name or something like that. So how do people know what caste one belongs to? I am asking as untouchability there seem to be at same level as Karnataka and Andhra Pradesh who use surnames.
