Speaking to reporters here, he sought to know why Rajinikanth had not spoken up when a group of people in Karnataka threatened to prevent the release of "Baahubali" featuring Sathyaraj in the cast and was now swearing by Tamil.
Last month, Kannada outfits had threatened to stall the film's April 27 release protesting alleged controversial remarks by Sathyaraj, who plays the role of Kattappa.
However, they withdrew the protest after the actor expressed regret over the comments made by him nine years ago during the Cauvery row.
The remarks by Rajnikanth are not acceptable, he said.
