Religious believers ask me all the time if I think all religious believers are stupid. My answer to this question is almost always the same. “Of course not; smart people can believe really stupid things too.” There is no doubt that the belief in the all-powerful god as described in the Torah/Bible/Koran based off of no valid evidence is stupid. Depending on how serious this belief is taken, it can even be ridiculously stupid. It would be like me telling people that Voldemort is real based off of my reading of the Harry Potter books. Link.
