I Gandhi was responsible for criticized the untouchables.
As I said before I am nonviolence nationalist leader of India, led a Salt March to protest the British salt tax. I believed that the salt tax was unjust and as such, all just people had a responsibility to break the law and make their own salt.
The Salt March is going to be the beginning of the end for the British imperialist. Indians demonstrated to the world the unjust nature of British imperialism in India.
