Islamic Morality
Americans, and most Westerners assume, like I used to (before I started studying about Islam) that Islam is just another religion -- as I've said before, strawberry-flavored belief to Judaism's chocolate and Christianity's vanilla.

It is not.

Now, of course, most Muslims don't engage in the evil that Islam demands, but that doesn't change the fact that Islam demands all sorts of evil from its followers, and that there are quite a few who carry this evil out.

Gregory M. Davis explains here with a bit about how, under Islam, Mohammed is to be seen (and emulated without question) -- and what a hideous person Mohammed actually was:

Because Muhammad is himself the measuring stick of morality, his actions are not judged according to an independent moral standard but rather establish what the standard for Muslims properly is.

Volume 7, Book 62, Number 88; Narrated Ursa: The Prophet wrote the (marriage contract) with Aisha while she was six years old and consummated his marriage with her while she was nine years old and she remained with him for nine years (i.e. till his death).

Volume 8, Book 82, Number 795; Narrated Anas: The Prophet cut off the hands and feet of the men belonging to the tribe of Uraina and did not cauterise (their bleeding limbs) till they died.

Volume 2, Book 23, Number 413; Narrated Abdullah bin Umar: The Jews {of Medina} brought to the Prophet a man and a woman from amongst them who have committed (adultery) illegal sexual intercourse. He ordered both of them to be stoned (to death), near the place of offering the funeral prayers beside the mosque.

Volume 9, Book 84, Number 57; Narrated Ikrima: Some Zanadiqa (atheists) were brought to Ali {the fourth Caliph} and he burnt them. The news of this event, reached Ibn 'Abbas who said, "If I had been in his place, I would not have burnt them, as Allah's Apostle forbade it, saying, "Do not punish anybody with Allah's punishment (fire)." I would have killed them according to the statement of Allah's Apostle, "Whoever changes his Islamic religion, then kill him."

Volume 1, Book 2, Number 25; Narrated Abu Huraira: Allah's Apostle was asked, "What is the best deed?" He replied, "To believe in Allah and His Apostle (Muhammad). The questioner then asked, "What is the next (in goodness)?" He replied, "To participate in Jihad (religious fighting) in Allah's Cause."

In Islam, there is no "natural" sense of morality or justice that transcends the specific examples and injunctions outlined in the Quran and the Sunnah. Because Muhammad is considered Allah's final prophet and the Quran the eternal, unalterable words of Allah himself, there is also no evolving morality that permits the modification or integration of Islamic morality with that from other sources. The entire Islamic moral universe devolves solely from the life and teachings of Muhammad.

Here's a bit on jihad:

The author of the 'Majma' al-Anhar fi Sharh Multaqal-Abhar', in describing the rules of jihad according to the Hanafi School, said: 'Jihad linguistically means to exert one's utmost effort in word and action; in the Sharee'ah {Sharia -- Islamic law} it is the fighting of the unbelievers, and involves all possible efforts that are necessary to dismantle the power of the enemies of Islam including beating them, plundering their wealth, destroying their places of worship and smashing their idols. This means that jihad is to strive to the utmost to ensure the strength of Islam by such means as fighting those who fight you and the dhimmies {non-Muslims living under Islamic rule} (if they violate any of the terms of the treaty) and the apostates (who are the worst of unbelievers, for they disbelieved after they have affirmed their belief).

It is fard (obligatory) on us to fight with the enemies. The Imam must send a military expedition to the Dar-al-Harb {House of War -- the non-Muslim world} every year at least once or twice, and the people must support him in this. If some of the people fulfill the obligation, the remainder are released from the obligation. If this fard kifayah (communal obligation) cannot be fulfilled by that group, then the responsibility lies with the closest adjacent group, and then the closest after that etc., and if the fard kifayah cannot be fulfilled except by all the people, it then becomes a fard 'ayn (individual obligation), like prayer on everyone of the people.
