The non communal (i.e. Non Hindu-fascist, totalitarian) political parties kept warning people of the riot wing agenda and when in power they didn't do enough (enough) to meaningfully change the circumstances. Later on the fascists (BJP and its ideological allies) became invincible because people didn't trust the 'boy who called wolf' (the boy was right each time, in this case the wolf would don sheep's clothing when people showed up). It no longer matters to the people that the BJP are the wolf.
