Can't see your point.
Are you saying that theologically misleading Islam is creating the violence?
Your viewpoint is in the minority of one.
To expand my other post, "Fundamentalism" was originally a protestant movement and we generally associate the modern term with orthodoxy or early expressions of the religion in question. Groups like Al Qaeda though aren't really based on early expressions of Islam or based on formal Islamic Orthodoxy. It's one reason why terrorist groups tend to have an ideological head like Osama bin Laden was. They need that person for theological direction. It largely stems from the 50's and 60's and a man named Sayyid Qutb. Qutbism is generally a foundation thought on which a number of modern international jihadist groups based themselves and Qutb was a major player because of his utilization of Ijtihad, (which had been closed in formal institutions for centuries), to create a new ideological path for Muslims.
International jihadi terrorism isn't a throwback to some former time, it is a relatively new Islamic ideology, and while strict, it isn't, well: fundamentalist.
