“Indeed, the truths that he taught he mingled with many fables and with doctrines of the greatest falsity. He did not bring forth any signs produced in a supernatural way, which alone fittingly gives witness to divine inspiration; for a visible action that can be only divine reveals an invisibly inspired teacher of truth. On the contrary, Muhammad said that he was sent in the power of his arms – which are signs not lacking even to robbers and tyrants… (continues below) –
…What is more, no wise men, men trained in things divine and human, believed in him from the beginning, Those who believed in him were brutal men and desert wanderers, utterly ignorant of all divine teaching, through whose numbers Muhammad forced others to become his followers by the violence of his arms. Nor do divine pronouncements on the part of preceding prophets offer him any witness. On the contrary, he perverts almost all the testimonies of the Old and New Testaments by making them into fabrications of his own, as can be seen by anyone who examines his law. It was, therefore, a shrewd decision on his part to forbid his followers to read the Old and New Testaments, lest these books convict him of falsity. It is thus clear that those who place any faith in his words believe foolishly.” – Saint Thomas Aquinas.
“The ambassador answered us that [the right] was founded on the Laws of the Prophet, that it was written in their Koran, that all nations who should not have answered their authority were sinners, that it was their right and duty to make war upon them wherever they could be found, and to make slaves of all they could take as prisoners, and that every Mussulman who should be slain in battle was sure to go to Paradise.” – Thomas Jefferson.
“Christianity is not the creed of Asia and Africa at this moment solely because the seventh century Christians of Asia and Africa had trained themselves not to fight, whereas the Moslems were trained to fight. Christianity was saved in Europe solely because the peoples of Europe fought. If the peoples of Europe in the seventh and eighth centuries, on up to and including the seventeenth century, had not possessed a military equality with, and gradually a growing superiority over the Mohammedans who invaded Europe, Europe would at this moment be Mohammedan and the Christian religion would be exterminated. Wherever the Mohammedans have had complete sway, wherever the Christians have been unable to resist them by the sword, Christianity has ultimately disappeared.” – Theodore Roosevelt.
“… he [Muhammad] declared undistinguishing and exterminating war, as a part of his religion, against all the rest of mankind…The precept of the Koran is, perpetual war against all who deny, that Mahomet is the prophet of God.” – John Quincy Adams.
“Immediately after his death the conquests began, and they proceeded with rapidity… Westward expansion (except in Sicily and Southern Italy) was brought to a standstill by the defeat of the Mohammedans at the battle of Tours in 732, just one hundred years after the death of the Prophet…” – (and) – “It was the duty of the faithful to conquer as much of the world as possible for Islam… The first conquests of the Arabs began as mere raids for plunder, and only turned into permanent occupation after experience has shown the weakness of the enemy…” – Bertrand Russell.
“How dreadful are the curses which Mohammedanism lays on its votaries! Besides the fanatical frenzy, which is as dangerous in a man as hydrophobia in a dog, there is this fearful fatalistic apathy. The effects are apparent in many countries; improvident habits, slovenly systems of agriculture, sluggish methods of commerce and insecurity of property exist wherever the followers of the Prophet rule or live. A degraded sensualism deprives this life of its grace and refinement, the next of its dignity and sanctity. The fact that in Mohammedan law every woman must belong to some man as his absolute property, either as a child, a wife, or a concubine, must delay the final extinction of slavery until the faith of Islam has ceased to be a great power among men… Individual Moslems may show splendid qualities, but the influence of the religion paralyzes the social development of those who follow it. No stronger retrograde force exists in the world…” – Sir Winston Churchill.
And also to be taken into account in the current context:
“The Pope gets ridiculed every day, but you don’t see Catholics organizing terrorist attacks around the world.” – Salman Rushdie.
“I don’t care if they’re offended – I’m offended every day.” – Tommy Robinson, English Defence League.
And let’s not forget that we, through our slavish devotion to Israel, are not innocent either:
“The Muslim world correctly interprets these wars and general aggression by western nations as being in support of the Zionist state, and therefore when they seek retaliation, it seems ‘normal’ for them to attack targets in both Israel and the West – hence the repeated Islamist terror attacks in London, Madrid, France, Germany, America and elsewhere.” – David Duke.
