Infidel - from the latin infidelis. Fidelis, Faithful, Loyal, True. Infidelis, Unfaithful, Disloyal, Untrue.
Major Nidal Malik Hasan may have indulged himself in tirades against the "infidels", yet in fact Hasan himself was the perfect embodiment of the infidel, the unfaithful and the disloyal. Nidal Malik Hasan betrayed the country of his birth and his oath of enlistment, he plotted treachery against those to whom he owed his service, he repaid the generosity of the country that had taken in his parents and of the United States military by plotting murder against them.
While the Arabic Kufr is often mistranslated as "infidel" in practice means anyone who is a non-Muslim by way of rejecting the authority of Islam and the revelation of Mohammed. To become a Muslim is as simple as reciting the Shahada, the twelve word statement by which one accepts the supremacy of Islam's deity, Allah and its prophet, Mohammed. To refuse to do so, regardless of whether you live in Bombay, Tokyo or North Dakota, marks you as a Kufr, as a rejecter of Islam's authority over all mankind.
By marking Mohammed as the last prophet to mankind, Islam makes Sharia law and the Koran uncontestable. Mankind has two choices, the same two choices that the people of the Middle East had when Mohammed's hordes poured down on them with a lust for murder and loot in their hearts, to recite the Shahada or die. When a suicide bomber detonates himself aboard an airplane or a grinning bearded terrorist slashes the throat of his unarmed captive or a grim group of Madrassa students armed with AK-47's open fire in a public square, they are following that same momentum that demands either acceptance of Islam or death.
The war against Israel, the war against Europe, America, China, India and every non-Muslim country on the globe, which has had the misfortune of being cursed with a Muslim minority, follows that same exact narrative in which Muslims wage war against it to make supreme the Koran and the religion of Mohammed. Though this war may be dressed up in class warfare rhetoric and nationalism, it is ultimately a religious war being fought by way of terror, much as Mohammed's followers originally fought it. Its mandate is religion. Its endgame is religion. And from the religion of Islam it draws its absolute supremacy over all human norms, dissolving all obligations and oaths in the name of Allah and his prophet.
And so middle class doctors in the US and the UK plot murder because they are "oppressed". Oppressed by living in countries to whom they feel no loyalty, from whom they have taken everything, and which they would rather kill than leave. That dissonance between the benefits they take in and the loyalty they do not feel marks their oppression. An oppression they can only resolve through mass murder. Rather than abiding sincerely by the values of the country in which they live or leaving it, they instead demand at knifepoint, that it follow their values instead.
This is the nature of the Muslim Infidel who takes but never gives. Who swears false oaths and takes on hollow obligations, who lies easily in the name of his deity of death, who pays no heed to any laws, but his own. The genius of Mohammed lay in his dissolution of all laws in favor of his own, thereby upending all old laws, treaties and obligations. To recreate oneself all a man had to do was recite the Shahada, and he would immediately be on the right side of a new and bloody law.
The endless plaint of Muslim victimization is a cynical ploy by those who wish to rule, rather than be ruled. The Muslim in non-Muslim countries typically enjoys more freedom than he does at home. And that is his complaint. He is not free to force women to walk a pace behind him, to beat his children and murder his daughters if they disobey him, and to know that all non-Muslims are beneath his feet. And what good is freedom to him if he cannot have these things?
Tolerance humiliates the Muslim, for in his storied past it was always he who had the choice to extend tolerance to the Kufr who were his social and political inferiors. The Muslim does not wish to be tolerated, he wishes to be obeyed. He does not want his beliefs respected in a plurality of beliefs, thereby equating them with the horrid beliefs of those he despises. He wishes that Islam alone be recognized as a true and unique belief, as the one true faith for all mankind. For by recognizing this, he becomes superior through it.
By embracing Islam, the Islamic Infidel wins the legal and moral right to be unfaithful, cruel, barbaric, sadistic and a thousand other things-- so long as he does them, at least putatively, in the name of Islam. There is no deity but Allah, cries the Muslim, and Mohammed is his prophet. Meaning that he has sown up the ownership of the Creator and assured the inferiority and the rightlessness of all who do not cry likewise. Cry Allah for Mohammed, and you have automatically become superior to all the Kufr. But that cry is the cry of the faithless infidel, who populates the lands of the Kufr and mimes his friendship until the day he sees his chance and his hand fumbles for his bomb belt.
