Adding to this..
Still there's untouchability exists in rural villages of TN, which affect lower caste people deeply.
- Lower caste people are not allowed to walk in certain streets, where higher caste lives.
- There will be 2 glasses (Glass and aluminium) in every tea shop of some villages. Lower caste should drink in Aluminium sitting in the ground, whereas Glass is for higher caste.
- Still higher caste people (maybe a poor) wash the place (in home mostly) with water, where lower caste person (maybe in a high position) sat.
Even, there are 2 graveyards in some villages, one (will be within the village) for higher caste and normal people and one for lower caste.
When it comes to untouchability, people other than lower caste (all) form a group and lower caste will form another group..
