Bernard Lewis (Cleveland E. Dodge Professor Emeritus of Near Eastern Studies at Princeton University) comments:
Two stereotypes dominate most of what has been written on tolerance and intolerance in the Islamic world. The first depicts a fanatical warrior, an Arab horseman riding out of the desert with a sword in one hand and the Qur'an in the other, offering his victims the choice between the two. This picture […] is not only false but impossible […]. The other image, almost equally preposterous, is that of an interfaith, interracial utopia, in which men and women belonging to different races, professing different creeds, lived side by side in a golden age of unbroken harmony, enjoying equality of rights and of opportunities, and toiling together for the advancement of civilization. Both images are of course wildly distorted; yet both contain, as stereotypes often do, some elements of truth. Two features they have in common are that they are relatively recent, and that they are of Western and not Islamic origin.[6]
It is only very recently that some defenders of Islam began to assert that their society in the past accorded equal status to non-Muslims. No such claim is made by spokesman for resurgent Islam, and historically there is no doubt that they are right. Traditional Islamic societies neither accorded such equality nor pretended that they were so doing. Indeed, in the old order, this would have been regarded not as a merit but as a dereliction of duty. How could one accord the same treatment to those who follow the true faith and those who willfully reject it? This would be a theological as well as a logical absurdity.
The rank of a full member of society was restricted to free male Muslims. Those who lacked any of these three essential qualifications -- that is, the slave, the woman or the unbeliever -- were not equal. The three basic inequalities of master and slave, man and woman, believer and unbeliever, were not merely admitted; they were established and regulated by holy law.
