Blaming RSS for Gandhiji's murder is like blaming Congress for the mass murder that took place during the partition. Just because Jinnah was a member of Congress between 1906 and 1926.
Entertainment industry (Anurag Kashyap, Aamir Khan, Shirish Kunder, etc) is on mission to save Indian secularism and culture, which RSS is otherwise killing, by it's maligning communal propaganda.
