There different atheists of different stripes. The ¨new atheists¨ of which dawkins is a perfect example, seem to be angry, very hostile to religion, crass in their words, and overall in actions anger many atheists. There is a great representation of them in this forum. Whenever there is a thread regarding Christian thought or doctrine, they fall over themselves to intrude, jeer, and generally disrupt on a thread in which they haven the slightest interest.
As to your use of the word ¨ Fundamentalism¨, I think you are really unclear as to what it means. Fundamentalism simply means believing in all the fundamental, foundations of ¨X¨. As applied to religion, it means a person who accepts and believes the fundamental doctrines of a faith structure. It has nothing to do with fear, or a closed mind, and certainly should be taught to the children of the parents that accept it. The concept of God is incoherent ? Nonsense. What is incoherent is the idea the universe created itself, that life created itself from the rain runoff from rocks and that the entire, huge universe, ordered itself so perfectly and beautifully with laws keeping it all working, purely by a chance that is so virtually impossible as to boggle the mind.
