Question

Why attitude of people should be changed to eradicate untouchability

Answer 1

Untouchability, in its literal sense, is the practice of ostracising a minority group by segregating them from the mainstream by social custom or legal mandate.

The term is most commonly associated with treatment of the Dalit communities in the Indian subcontinent who were considered "polluting", but the term has also been loosely used to refer to other groups, such as the Cagots in Europe, and the Al-Akhdam in Yemen.
