Sir — This refers to the article, “Some have a problem with the Tricolour too” (March 1) by A Surya Prakash. The most potent enemy of the Rashtriya Swayamsevak Sangh and the Bharatiya Janata Party is their own silence and not knowing when to talk, what to talk and how to talk. A proper verbal attack on the Congress and the communists shall send them reeling and running for cover, for decades. Unfortunately this is not being done.
