If we study the British archives befor 1947. I say if we study and not just read. Jinnah, Gandhi and Nehru all three of them allowed themsleves to be used by british to polorise the Hindu-Muslim community. Also study how Gandhi and Nehru treated Bhagat singh, Netaji Bose, Savarkar, etc.
Hence if we call Gandhi a MAHATMA. Then what's wrong in calling Jinnah a secular leader?
