There are violent people in all religions, but many civilized Muslims too. I've met a few here in L.A. who are secular, the women in modern dress and they have careers.
There are 146 wars going on in this world today. Of those 146, 142 involve Islam / Muslims.
That number's been circulating the internet, and I suppose talk radio too. I don't know how accurate it is. But there are some billion Muslims in the world, so it's only natural that people of Muslim faith are "involved" in many wars. How many Christian nations were "involved" in World Wars One and Two?
Mohammed was a terrorist and participated in many killings....
"Terrorist" is a modern word. Another way to look at it is that Mohammed was a "warrior" -- same as Charles the Great (who was crowned Holy Roman Emperor for his war-making), the Cursaders, the Israelists (who were aggresors as much as aggresed against), and a whole host of nominally Christian or Jewish kings and leaders. Moses was arguably as much a warrior/terrorist as Mohammed. Moses came upon Canaan and waged an aggressive war on them.
I don't know that Mohammed was any more a "terrorist" than other rulers of his era. Sure, Christ and Buddha were peaceful, but many religious leaders (popes too) were warriors.
I think there's cruelty in the Bible. It's an uneven book, probably because it has many authors. Look at all the punishments that God inflicts. There's one story about a guy who's helping carry the Arc of the Covenant, and he slips against it, and thus is stricken dead.
