This may be a surprising thread coming from myself, an agnostic, who probably fits many definitions of "atheist." However, I'd like to address my opinion of many individuals in the atheist community, particularly young people who have left the church and been influenced by the New Atheist movement. The arrogance of many of them is laughable. Many of them seem to think that because they have read "The God Delusion" or some such book, that they are now somehow enlightened and intellectually superior to the rest of the population who are not atheists. This is certainly not true, and it is somewhat laughable and somewhat disconcerting, because falsely believing oneself to be smarter than one actually is can lead to a lessened desire for learning new things. Many of these young "new atheist" types are deluding themselves into the belief that they are thinking for themselves, when in actuality, they are simply letting popular atheists like Dawkins, Harris et. al. do their thinking for them.
There are many theistic intellectuals that I can guarantee were much more intelligent than any of the know-it-all atheist keyboard warriors of today. For instance, Rene Descartes, Blaise Pascal, and Isaac Newton were all brilliant mathematicians (definitely some of the smartest people in all of recorded history) and also devout Christian believers. The point of my post is to simply offer my opinion on many of the atheists, particularly young atheists, that are found so abundantly on the Internet today and seem to love looking down their noses at others whose beliefs differ from theirs. The fact is, you're not as smart as you think you are, so don't forget to listen to the thoughts of others, and keep an open mind.
