The history of Islam's practitioners speaks for itself. Islam, by the very nature of its own doctrine, history and by the actions of its followers has shown itself to be the existential enemy of Western civilization. Dr. Andrew Bostom's The Legacy of Jihad: Islamic Holy War and the Fate of Non-Muslims provides insight into the Islamic mindset and what its ascendancy might mean for the rest of us:
Lee Harris' outstanding work, The Suicide of Reason: Radical Islam's Threat to the West explains why and how the West's days may be numbered. We are our own worst enemy unless we face up to the hard choices necessary to remain free and prosperous.
If anyone is still having trouble wrapping their minds around the fact that Western civilization does in fact have mortal and existential enemies, take a quick turn through Lee Harris' Civilization and Its Enemies
Let us also dispense with the idea that Islam is a religion. Islam is not so much a religion as it is a supremacist, totalitarian political ideology, a destructive and murderous meme impervious to moderation or change, and with a narrowly circumscribed set of rituals that define every aspect of its followers lives. As for 'tolerance', here's a quote from the Muslim Brotherhood and their mission in the U.S, calling for...
"...a kind of grand Jihad in eliminating and destroying the Western civilization from within and sabotaging its miserable house by their hands and the hands of the believers so that it is eliminated and Gods religion is made victorious over all other religions."
Speaking to the Islam is a religion of peace," assertion that we hear from Muslims and ignorant (yes, ignorant) Westerners, when Muslims assert that Islam is a religion of peace they are not engaging in al taqqiya, they are actually making an assertion in good faith.
The problem lies in the fact that Islam has, from the Western point of view, a defective concept of peace. In semitic languages like Arabic, the consonants are the root of the word: islam = submission, and salam = peace have the same root, slm.
The only concept of peace in Islamic jurisprudence is the peace between the conqueror and the conquered, between master and slave. There is no concept of a negotiated peace between nations in Islamic law (note that law is the defining property of Islamtheir clerics are jurists, schools of Quranic interpretation are called fiqh, a legalistic term)Muslims may negotiate a hudna or armistice of limited duration with non-Muslim, but not a definitive enduring peace.
In that regard, Islam was, is and will be a serial murderer of entire cultures and peoples. This is precisely what Islam has done throughout its entire 1400 year history. This is what it has done whenever it has finally gotten the upper hand in whatever culture it has infiltrated. This is what has been inextricably interwoven into the DNA of its operating system. Those whom Islam does not destroy, it enslaves, diminishes and impoverishes. Islam strives for the conversion, enslavement or death of all who do not conform to its sadistic and cruel vision of Mankind. Islam cannot be reformed in the light of our Western values of humanity and freedom. Were that so, it would no longer be Islam. For its psychopathic and cruel misogyny alone, Islam is an abomination and worthy only of extinction.
