Sir — In 1967, Kanu Sanyal led a peasant protest which later became an anarchist Naxalbari movement. The suicide by a farmer at an Aam Aadmi Party rally shows the dangers of mass hysteria that modern-day extremists create. All democratic minded people should take the incident as a warning that Mr Arvind Kejriwal is being a modern-day Kanu Sanyal and leading us to the path of anarchy.
