"It is a significant fact that while in India, the Government discourages communal groups and parties, in Pakistan no group or parties other than communal are encouraged. A Pakistan Peoples’ Congress is inconceivable. When the Hindu leaders of Sind planned the establishment of a political party which might draw its membership from people belonging to various religions, the reply of the Pakistan Government was characteristic. The Hindus of Sind, (such of them as are still there) might have a Hindu Party, but not one which Muslims also might join. In the Muslim State of Pakistan, no Muslim may join any organization other than a purely Muslim one. It is such an attitude which bred the riots of 1946 and 1947-Calcutta, Noakhali, N.-W. F. P., the Punjab, Sind and Bahawalpur."
