Former Union Minister P. Chidambaram on Friday said he was glad that former President Pranab Mukherjee told RSS as to what was wrong with its ideology."Happy that Mr Pranab Mukherjee told the RSS what is right about Congress' ideology. It was his way of saying what is wrong about RSS' ideology," Chidambaram tweeted on Mukherjee's visit to Nagpur on Thursday.Speaking at the 'Tritya Varsh Varga' or the last leg of the three-year Rashtriya Swayamsevak Sangh (RSS) training programme at the RSS headquarters in Nagpur, Mukherjee that India's multiple faiths and cultures made it tolerant and that the soul of the nation resided in its pluralism and secularism."This plurality of our society has come through assimilation of ideas over centuries. Secularism and inclusion are a matter of faith for us. It is our composite culture which makes us into one nation," he said.His visit to RSS headquarters had, however, drawn a lot of flak from the Congress party, including from his daughter Sharmistha Mukherjee.
