Below is a link to direct quotes from the Quran/Koran on this subject. They are taken from an official administrative complaint against the San Luis Coastal Unified School District. Violence advocated against infidels is not related to age but is for the sin of non-belief. http://www.blessedcause.org/complaint/Quran%20Koran%20Quotes.htm
Wow. That's scary. Not as much the Koran quotes (I've seen just as much hostility towards "others" in the Old Testament. Jericho, anyone? Wild bear let loose on 42 children?) but the argument from the complainers that pluralism is evil. They seem to really dislike the Constitution of the United States. By the way: I found nothing in those quotes that advocate killing infidel children, only general, vague hostility towards "unbelievers". The quotes themselves seem to be accurate, according to this searchable Koran site: http://www.islamicity.com/MOSQUE/ARABICSCRIPT/AYAT/8/8_55.htm By the way II: unsurprisingly, the Koran seem full of contradictions. Along with all the fury towards "unbelievers", there's this: 17:33 Nor take life - which Allah has made sacred - except for just cause. And if anyone is slain wrongfully, we have given his heir authority (to demand qisas or to forgive): but let him nor exceed bounds in the matter of taking life; for he is helped (by the Law). 107:1-7 Seest thou one who denies the Judgment (to come)? Then such is the (man) who repulses the orphan (with harshness), And encourages not the feeding of the indigent. So woe to the worshippers Who are neglectful of their prayers, Those who (want but) to be seen (of men), But refuse (to supply) (even) neighbourly needs.
5:69 Those who believe (in the Qur'an), those who follow the Jewish (scriptures), and the Sabians and the Christians,- any who believe in Allah and the Last Day, and work righteousness,- on them shall be no fear, nor shall they grieve. In short, I'll go by the words of President Bush. Islam isn't evil, and the WoT shouldn't be construed as a war on Islam.
