Ibn Warraq's book will either be ignored with deadly thoroughness or cause an enormous riot. - Ibn Warraq

As early as the thirteenth century, thinkers like Nur-ud Din Mubarak Ghaznavi, working at the court of Sultan Iltutmish [ruled 1211-1236] set the aggressive tone of Islamic presence in India. Nur-ud Din elaborated the doctrine of Din Panahi [protection of religion], by which Islam had to be defended from the defiling Hindus who were idolaters who must be kept in their place, and insulted, disgraced, dishonoured and defamed. Ziauddin Barani [Diyā al-Dīn Baranī: 1285-1357] who was an Indian jurist, historian, political thinker, writer, and a companion of Sultan Muhammad b. Tughluq [1309 –1388], wrote a Fürstenspiegel, a Mirror of Princes, akin to Machiavelli’s The Prince, the Fatāwā-yi Djahāndārī, in order to educate the de facto rulers of the day, the sultans, in their duty towards Islam in an age of corruption. Barani advises sultans to enforce the sharī‘a, to curb unorthodoxy ( especially speculative philosophy, falsafa), to degrade the infidel, who must be treated harshly. The Sultans must fight like the Prophet until all people affirm that “there is no God but Allah.” It is the duty of Muslim rulers to overthrow infidelity, uproot it completely, and apply the Holy Law, the Sharia on all. Firuz Shah Tughlaq (1309 – 1388), the Turkic Muslim who reigned over the Sultanate of Delhi (1351-1388) carried on the intolerant tradition of the early invaders, and believed that by extirpating Hinduism wherever possible he served God.

There are many reasons behind it. Bat Ye'or describes one of them in her new book "Eurabia": not long after the Second World War, the Europeans and especially France created a European-Arab axis, to lessen the influence of the USA. There were bilateral agreements. The EU launched Arab exchange programmes and financed Arab NGOs, creating strong European-Arab networks. If they were now to criticise anything about Islam that would upset their allies in the axis. Another reason is multiculturalism.

After their spectacular conquests, the Arabs were unwilling to concede equality to the non-Arab converts to Islam, despite Islamic doctrine that expressively forbade discrimination. But for the Arabs there were the conquered and the conquerors ... The Arabs ruled as a sort of conquistador tribal aristocracy.
