I do believe that religion is generally a crutch for people, for whatever reason. It is also, in a larger sense, a power structure that allows folks to be manipulated in subtle and very insidious ways. What better way to control people then through their beliefs? With religion, there is always a way to motivate believers, by setting up and controlling their perceptions of "the others"; those who do not share their beliefs. Often, the others become scapegoats for the power-mongers. History bears out my viewpoint. Religion may occasionally benefit individuals, but such benefits are temporary. In the long run, religions can only do harm, both personally and on a global scale. Most of the time, the personal harm of a religion is insignificant and only involves small prejudices, loss of critical thinking ability and objectivity, etc.
Witness the constant manifestations of nonsensical thinking: Qi, John Edwards, the Pet Psychic, UFOs, Bigfoot, homeopathics, fortune-telling, Miss Cleo, etc. All of this can be directly traced to religious training.
