I need to find the most reliable information possible...
Let me tell you a story. Your grandfather during the festival of Diwali would make sure to visit every worker and untouchable on campus and give them a box of sweets after embracing them. Not all people believe in this evil system.
Mom, why does everyone treat the untouchables so poorly? Why do they stay away from them, aren't they humans like us?
The caste system is outlawed now, and society is making an effort to stop this discrimination and give back to the untouchables.
Determined to find accurate information, I went to the most reliable source there was: Google (and then Wikipedia.) I was astounded by the history of the Caste System and the terrible treatment of the untouchables.
After talking with my mom I began to feel better but realized that a lot still had to be done.
