I just dont think that Justice KGB is a Buddhist or Ambedkarite. Though belonging to the dalit community, the Justice was born in an area which was academically very rich many centuries ago. I believe that except for certain petty tribes still living in forests, most of the dalits in Kerala are either worshipping the same Hindu gods that the upper caste worship or are converted Christians. Ambedkar is hardly a draw in Kerala...so do I feel.
