For the RSS, it is important that OBCs and Dalits join the organization if it is to become champion of the interests of all Hindus and not just the upper castes. It will also likely to increasingly get its cadre from the OBCs and Dalits. Can its deeply Brahminical leadership convinced of the superiority of the upper castes change itself to accommodate OBCs and Dalits in its leadership? 

They must.

Gone are the old Charnamrit Days.

They will never return. 

The old masters must not attempt a mass sucide or a burial of the Sangh.
