I agree that fiat creates the problem, but that can't be used to excuse murder or the culture that caused that guy to commit murder. I have actually read the Quran, and the language used in that book is so violent that it actually makes a strong case for censorship - I'm against censorship, but it clearly has an influence on people's behavior. That guy murdered 3 little girls... One was 7 years old. And you can't tell me that's only because of fiat - Muslim cultures have been mutilating young women for centuries, in their own countries, way longer than fiat money has existed. I didn't know he was born in the UK, but it doesn't matter - Islam promotes violence.  

 1) I don’t know for sure but I don’t think he was Muslim.
2) Islam doesn’t have a monopoly on violence committed in its name. 

 He was muslim. Have you noticed that state run news media never say when the perpetrators are Muslim? And Muslims have been staging counter protests, which are VERY violent, while the state run media calls the native British protestors violent. It doesn't take much digging to find videos, despite the regime arresting people who post real information.
