That's fair, but you still have to give evolution time to work. I mean, you have to. There's no other way you or anybody else can do anything about it. We are part of the same planet and there's no way we can avoid each other. The globalisation is speeding up. There's loads of muslims in USA. One in ten Swedes where born in an other country or their parents where. We've got a huge mosque in central Stockholm. Arabs and the Arab culture is everywhere now.
Not devolved but froze. They thought they had the worlds most advanced and enlightened culture, (which was true at first). They where Europes and the regions only culture that allowed followers of other religions to stay and live, which for the time was extremly progressive. They had big churches and synagogues that where under the protection of the sultan. What went wrong is that the evolution of the culture stopped and Europe wizzed past them. The same thing that happened to the Roman empire where the "barbarians" ended up having a far superior culture.
If history teaches us anything it's that whenever people become chauvinist about their culture it stops evolving and in time becomes obsolete. Let's try to avoid that ok?
With superior culture I mean the most tollerant culture that allows for the maximum amount of diversity and still holding together. According to the US researcher Richard Florida, cultures like this have historically always been and are always the richest and most technologically advanced cultures in the world.
He floated the concept of gay-index as a way to measure this. Cities that are gay friendly, ie has the highest proportion of openly gay citizens has invariably the highest per capita income. Tollerance makes money. I agree with him 100%. In other words, a cultures superiority can be measured in money. I like things that can be measured.
I don't think Islamic terrorism is about trying to convert anybody. It has to do with what muslims consider is the "holy lands" and about attacking any un-believer that dares invade or colonialise it. That's at least what Osama said was his driving force and a good summary of what Islamic terrorisms main philosopher said, Qutb.
