A person who thinks fundamentalistically adheres rigidly to traditional principles, rejects innovations and does not want to adapt to modern times. These principles can be political or religious convictions. For example, there are Christian fundamentalists who believe strictly that the Bible is the literal word of God. In their opinion, the Bible should be obeyed in all details, both in family life and political life. Islamic fundamentalism, which is also called Islamism, calls for precise adherence to the rules laid down in the Koran and to the Islamic laws. There are fundamentalists all over the world; they are often intolerant towards people who think differently from them. If they are fanatical, they can become dangerous to other people, particularly if they want to use violence to impose their views.
