Yes I have. Have you?
The spread of Islam was very slow and gradual, contrary to popular perception. Although the Arabs did conquer large swathes of territory under the first caliphs they did not forcibly convert the populations out of fear of mass rebellion. For the most part the administration of the Rashidun Caliphate and the subsequent caliphates was essentially a military administration which did not involve itself in the daily life of their subjects. They exercised considerable tolerance and this was a major factor in their rapid expansion.
In almost all territories that the Arabs conquered the spread of Islam followed a distinct pattern. First, there was the military conquest, where a small group of Arabs assume the role of the ruling military nobility. Then, there was the conversion of the upper classes to Islam, which was mostly voluntary because it was advantageous for the local upper classes to ally themselves with the ruling Muslims. This was followed by the spread of the Arabic language to all classes of the population (starting again with the upper), and only then with the spread of Islam to the majority of the population.
If we take the example of Egypt, the initial Arab conquest took place in the 7th century and Egypt was subsequently ruled by a nobility of around 70,000 Arabs. Gradually, the Egyptian upper classes converted to Islam and Arabic replaced Greek as the language of the elite. However, it was not until the 14th century that a majority of Egyptians were Muslims who spoke Arabic as a first language. The spread of Islam in India followed these same general steps, although the conquests were made by Turks who spoke Persian/Urdu rather than Arabs, but since India is a far larger and diverse country than Egypt, Syria, and the others, and because India was never fully conquered by any Muslim power, Islam did not spread to the same extent that it did in West Asia and North Africa.
The rest of your post concerning circumcision, Bannerjee, and Rip Van Winkle is unfortunately beyond my comprehension.
