To address the original topic of this thread, I just wanted to point out that it is incorrect to compare the attack on 9/11 with the Oklahoma bombing.
While Timothy McVeigh was a Catholic, he did not explode his bomb in the name of Catholicism. The Muslim extremists did, in fact, attack the infidel United States in the name of their beloved Islamic religion. Indeed, this attack inspired the widespread contempt for the religion of Islam that so many people harbour to this day.
But do not forget for one minute that the seemingly benign Catholic religion is no better. When it enjoyed the same theocratic stranglehold over it subjects as Islam enjoys today, it was no less bloodthirsty and intolerant.
Fortunately, democracy prevails over theocracy in North America and the terrible oppression of the Catholic Church's rule has been greatly reduced. (Although its disregard for molesting children, its contempt for homosexuals, its regard for women as second class, its obstruction of birth control to third world counties, are only some of the remnants of its previous glory days.)
The attack on 9/11 was nothing more and nothing less than a religiously inspired act of retaliation against the perceived "infidel nation" of the United States of America.
While the individuals who carried out this violent plan are considered "extremists", it is relevant to note that their beloved prophet, Muhammad, who single handedly created the Koran, was no less an extremist. He was a ruthless military commander who initiated merciless raids and wars against innocent peoples whom, he alone, judged to be infidels. Terrible atrocities are described in graphic detail in historical accounts of his reign of terror. For the reader not familiar with the religion of Islam, it is critical to understand that while the Koran is the Muslims' holy book, considered to be the word of god spoken directly through Muhammad, there is another book that is considered essential reading in order to fully appreciate the Koran—the Hadith. This account focuses on the life and actions of Muhammad. It is considered the model of behaviour to which every Muslim should aspire.
So if the 9/11 terrorists are to be condemned for their extremist acts of terror, I must point out that their prophet was an excellent role model and a most inspiring teacher.
