Is untouchability very old?
Yes, it has always been there. The “untouchables” could not enter a temple. While talking to a Rajput, the lower castes covered their mouths with the hand. The Rajputs used to be standing on the upper floor and the untouchables on the ground floor while talking. The upper castes encouraged untouchability. But now it has all changed. The Harijans can go to the temple, dance and sing freely.
