Leaders make controversial statements deliberately or by mistake?

In News Nation's special show, 'Bada Sawal', we discussed whether controversial statements are deliberately made by politicians or they simply commit mistakes. Recently in a rally, PM Modi pointed out all the controversial remarks made against him. Congress leader Sanjay Nirupam called PM Modi 'Modern incarnation of Aurangzeb', RJD leader Shivanand Tiwari said that all those who are trained by RSS need psychiatrists. Congress Priyanka Gandhi compared PM Modi with 'Duryodhana'.
