Why do India's Dalits hate Gandhi?

Dalits are granted all constitutionl rights freedom and liberty.Yes it's true that at some corners they are being subjected to inhumane treatments or are being manacled so as to contain them from their liberties but it is not the general case.I have my Dalit friends and they are happy and live comfortably.Its like places to places.There are some remote villages in India where illiteracy prevail and people in those areas are not comfortable with what they have .It's just like any other country in the world.

But still Dalits do not have to face suicide bombers... :)
