The Canadian writer, broadcaster, and liberal activist, Tarek Fatah was at his sharpest as a guest on Thursday evening at Firstpost Salon, educating and entertaining the audience with his erudition shorn of all political correctness. India should realise her potential, play global peacemaker and stop going after Aamir Khan, advised Fatah, who identifies himself as an Indian born in Pakistan; a Punjabi born in Islam; an immigrant in Canada with a Muslim consciousness.
