Fundamentalism, or extremism, of any kind can potentially be dangerous. Ultra-conservatism, ultra-liberalism, radical Christianity, radical Islam... any time a belief gets taken to a extreme, people become prepared to die - or kill - to uphold that extreme view.
Of course, simply having an extreme view isn't inerently harmful; but if that view gains a lot of support, and those supporters are prepared to back words with actions, then the rest of the population are in trouble.
