Not being religious in the slightest, I never understood the need for everyone to believe the same thing or follow the same traditions. Personally, George Carlin best describes why I don't partake in organized religion ( http://www.youtube.com/watch?v=MeSSwKffj9o ). Not because religion is bullshit, but because of religion's natural tendency to deteriorate in meaning over time. By this I mean since the self-identified inception of the religion (i.e., Christianity and the life of Jesus, Mormon's and the normal middle aged man with the most normal name possible..., Muslims and the Prophet Mohammed, etc...). Assuming that one/any of those inceptions or time markers are true and were real events, their veracity cannot be verified by virtue of the fact that the knowledge of those events was passed through time by human beings.
Human beings inevitably act for the their own interest - that could include making the ones you care about better off (implying that selflessness is possible and that selflessness can lead to a better/worse off overall state of affairs for society). When information passes through thousands of years, tens of hundreds of wars, etc..., and in the case of Christianity, is edited by a Monarch who also sat as a religious authority seeking "peace" between the different denominations, it is a perfectly reasonable inquiry to ask how accurate our interpretations are compared to the actual events (given their happening, regardless).
They are likely very different. I'll cite the famous reply to Dr. Bitch, or whatever the hell her name was who somehow overlooked that slavery of your nation neighbours was legal in such and so...while managing to receive strong support for her acknowledgement of the Bible's stern advice on "laying with another man." The bigger question is this: Who among human beings decides what is valid in religion, and (again, assuming a deity exists for purposes of discussion) how it should be employed? As far as I'm concerned, at least with respect to Roman Catholicism, the Bible has been edited thousands of times. Suppose it's a committee who decides; how do they decide? What influence those edits? Who oversees that the respectful deity in each faith approves? Can we verify that they do in fact approve? Or is the Vatican and the Church of LDS simply influencing the faith (which is a serious matter given the weight many place on it in their lives) of billions?
When people start thinking independently of whatever committee approves what they read on Sundays, things like this happen. I acknowledge that faith gives people hope and offers a platform for deep personal reflection, it is entirely possible to uphold those benefits while thinking critically and questioning everything you hear. When Mormons start leaving congregation, that's a strong sign that the light bulb has turned on.
