The Rashtriya Swayamswevak Sangh or RSS is being needlessly blamed for the mob-lynching of a man in Uttar Pradesh's Dadri and similar incidents of violence, General Secretary Bhaiyyaji Joshi has said. "We are in social life for 90 years. No one has raised such questions on intolerance. Whatever has happened we condemn that. Such incidents are not good for the society. But we need go deeper into such incidents. The truth must come out," Mr Joshi said.
