Why should untouchability be eradicated?

To regard our 70 million co-religionists as ‘untouchables’ and worse than animals is an insult not only to humanity but also to the sanctity of our soul. It is my firm conviction that this is why untouchability should be principally eradicated. Untouchability should go also because its eradication is in the interests of our Hindu society. Even if the Hindu society were to partially benefit from that custom, I would have opposed it with equal vehemence. When I refuse to touch some one because he was born in a particular community but play with cats and dogs, I am committing a most heinous crime against humanity. Untouchability should be eradicated not only because it is incumbent on us but because it is impossible to justify this inhuman custom when we consider any aspect of dharma. Hence this custom should be eradicated as a command of dharma. From the point of view of justice, dharma and humanism, fighting untouchability is a duty and we Hindus should completely eradicate it. In the present circumstances, how we will benefit by fighting it is a secondary consideration. This question of benefit is an aapaddharma (duty to be done in certain exceptional circumstances) and eradication of untouchability is the foremost and absolute dharma.
