Damn it, I am now no longer the only Abe on this board! 
Morpheus, others have pointed out that you should not confuse culture with religion. If you had read the Koran you would understand what I mean. Sure, Islam has a bad rep thanks to assholes like the Taleban, but before you assume anything else on the topic, read the Koran. I am not saying this to convert you (I am agnostic-atheist and no fan of any religion), but I think that it will give you a better idea on the topic. The Koran is, overall, a very gentle work. Some of the men who practise Islam are not, but do not confuse the idiocy of men with the value of particular religions.
As for countries flourishing under Islam–think about literacy rates all over the world, in the 7th and 8th centuries, and beyond. Pretty dismal. But wherever in the world Islam took root, children were taught reading and writing --formerly the domain of scholars, nobles, and merchants-- so that they might understand, memorize, and reproduce the Koran. This not only raised literacy rates, but had interesting side effects such as producing a large number of great poets, scientists, politicians, philosophers, etc. Go to Amazon and buy any book on the topic “tales of the Sufis” to see what I mean for didactic poetry and tales. Or look up the works of Ibn Sina, known in Latin as Avicenna, for examples of scientific work.
On the topic of women, I usually see Mohammed as a remarkable social engineer who turned a tribal system into an empire. In his time, baby girls were abandoned in the wilderness because poor parents were not willing to bear the costs that young women entailed (dowry, etc.). Mohammed came in and put an immediate stop to this practice. He once said, “heaven is at the feet of your mother”. He instituted modest dress codes for both sexes to minimize sexual tension, in order to enable men and women to exist side by side without the urge to steal or rape a vulnerable wife/daughter. My belief is that this was a good thing in the past, but it has been perverted in this day and age in some countries. While Mohammed sought to protect women, who were at high risk not just from the men they lived with but also from raiding tribes, some of today’s men are actively repressing women for their own reasons or cultures, not the reasons and culture of Islam.
Just consider the contributions made to the first wave of feminism in Egypt alone in the 19th century! (see http://holysmoke.org/fem/fem0035.htm). And consider that women in many Islamic parts of the world were able to own land and enjoy similar rights long before these rights were granted to many European counterparts!
You are the victim of misinformation. There is nothing in Islam that makes it a vicious religion. Keep in mind that Islam is quite young for a religion, not even 1.5 thousand years old. What was the situation with, e.g., Christianity in 500-700 years ago? Not ideal by any means, and far more contradictory and manipulative than Islam has ever been.
I will agree with you that Islam is sometimes used as a front for the oppression of women, the destruction of monuments, and other foolishness, but that is by no means grounds to say that Islam itself is a vicious religion. Some of its followers, yes; but you get that across all religions, not just Islam.
