And without reading the book you have recommended, I am familiar enough with the history of Islam to know that historically, both Christians and Jews were initially treated respectfully by the Muslims who considered those of all three faiths to be "Children of The Book" since they all drew their basic precepts from the same semitic roots. Such status left the Christians and Jews free from Muslim taxes, no small concession for any government.
[9.28] O you who believe! the idolaters are nothing but unclean, so they shall not approach the Sacred Mosque after this year; and if you fear poverty then Allah will enrich you out of His grace if He please; surely Allah is Knowing Wise. [9.29] Fight those who do not believe in Allah, nor in the latter day, nor do they prohibit what Allah and His Apostle have prohibited, nor follow the religion of truth, out of those who have been given the Book, until they pay the tax in acknowledgment of superiority and they are in a state of subjection. [9.30] And the Jews say: Uzair is the son of Allah; and the Christians say: The Messiah is the son of Allah; these are the words of their mouths; they imitate the saying of those who disbelieved before; may Allah destroy them; how they are turned away!
We all like to think of ourselves as rugged individualists. But when push comes to shove most of us are sheep who do what we are told. Worst of all, a lot of us become unpaid agents of whoever is controlling the agenda by enforcing the current dogma on the few rugged individualists who actually exist.
