I can't understand why b.r.ambedkar is sceptical about m k Gandhi. M k gandhi may appear as casteist. But at where m k Gandhi said that he is casteist ? See ! B r ambedkar ! To solve an evil like CASTEISM,one must "appear as casteist" in social system. Because social system is three dimensional unlike mind system. In three dimensional system,an evil can be solved or made itself solved only if one "appears as an evil" to retain both sides as good within themselves for third party. B r ambedkar may be lawyer but he certainly doesn't know social system and its ever-dynamic change. All b r ambedkar followers must note.
