SEE HERE I had the pleasure of visiting John Quincy Adams' house on a trip to my uncle Dick's 50th wedding anniversary some years ago. What struck me was the three story stone structure next to the house. It was Adams' library. We went in and my reaction was "I want one of these." I love books and so obviously did John Quincy Adams. Below are the quotes from Adams that are presented in the link. They present the views of one of our most educated presidents on the nature and dangers of Islam.
In the seventh century of the Christian era, a wandering Arab of the lineage of Hagar, the Egyptian, combining the powers of transcendent genius, with the preternatural energy of a fanatic, and the fraudulent spirit of an impostor, proclaimed himself as a messenger from Heaven, and spread desolation and delusion over an extensive portion of the earth. Adopting from the sublime conception of the Mosaic law, the doctrine of one omnipotent God; he connected indissolubly with it, the audacious falsehood, that he was himself his prophet and apostle. Adopting from the new Revelation of Jesus, the faith and hope of immortal life, and of future retribution, he humbled it to the dust, by adapting all the rewards and sanctions of his religion to the gratification of the sexual passion. He poisoned the sources of human felicity at the fountain, by degrading the condition of the female sex, and the allowance of polygamy; and he declared undistinguishing and exterminating war, as a part of his religion, against all the rest of mankind. THE ESSENCE OF HIS DOCTRINE WAS VIOLENCE AND LUST: TO EXALT THE BRUTAL OVER THE SPIRITUAL PART OF HUMAN NATURE.
Between these two religions, thus contrasted in their characters, a war of twelve hundred years has already raged. That war is yet flagrant; nor can it cease but by the extinction of that imposture, which has been permitted by Providence to prolong the degeneracy of man. While the merciless and dissolute dogmas of the false prophet shall furnish motives to human action, there can never be peace upon earth, and good will towards men. The hand of Ishmael will be against every man, and every man’s hand against him. It is, indeed, amongst the mysterious dealings of God, that this delusion should have been suffered for so many ages, and during so many generations of human kind, to prevail over the doctrines of the meek and peaceful and benevolent Jesus (Blunt, 1830, 29:269, capitals in orig.).

The precept of the koran is, perpetual war against all who deny, that Mahomet is the prophet of God. The vanquished may purchase their lives, by the payment of tribute; the victorious may be appeased by a false and delusive promise of peace; and the faithful follower of the prophet, may submit to the imperious necessities of defeat: but the command to propagate the Moslem creed by the sword is always obligatory, when it can be made effective. The commands of the prophet may be performed alike, by fraud, or by force (Blunt, 29:274).
[Finally comparing Christianity and Islam]
The fundamental doctrine of the Christian religion, is the extirpation of hatred from the human heart. It forbids the exercise of it, even towards enemies. There is no denomination of Christians, which denies or misunderstands this doctrine. All understand it alike—all acknowledge its obligations; and however imperfectly, in the purposes of Divine Providence, its efficacy has been shown in the practice of Christians, it has not been wholly inoperative upon them. Its effect has been upon the manners of nations. It has mitigated the horrors of war—it has softened the features of slavery—it has humanized the intercourse of social life. The unqualified acknowledgement of a duty does not, indeed, suffice to insure its performance. Hatred is yet a passion, but too powerful upon the hearts of Christians. Yet they cannot indulge it, except by the sacrifice of their principles, and the conscious violation of their duties. No state paper from a Christian hand, could, without trampling the precepts of its Lord and Master, have commenced by an open proclamation of hatred to any portion of the human race. The Ottoman lays it down as the foundation of his discourse (Blunt, 29:300, emp. added).
