I am giving credit where it is due and, this is why I appreciated Mohandas' sacrifices for his people - the upper caste Hindus.
Some reading of history might help you :) Many upper caste Hindus were against Gandhi and it was an upper caste Hindu who assassinated him.
It is necessary to point out an aspect of Gandhi's personality that made him source of unabated distrust and dislike in the eyes of hard core Hindus. Though he was devout Hindu, he had most amicable and warm relations with many who did not belong to the Hindu fold. As a result of this exposure he had developed an eclectic religious sense based on oneness of God and equality of all religions.
Caste divisions and untouchability prevalent among the Hindu social organisation distressed him immensely. He advocated and actively encouraged inter-caste marriages. Lastly he blessed only those marriages wherein one of the partners belonged to the untouchable castes.
He coined the term "Harijan" for the dalits, which means "God's children". Vested interests amongst high caste Hindus viewed this reformist and other religious programmes with bitter resentment. In course of time it developed into a phobia and thus he became an anathema to them.
