There is no automatism that commands any religion to be reformed by some point in time. We have this strange and fuzzy feeling about religion as something esoteric, something that only bothers you, something that gives you a nice feeling in dark times. No harm done, all the same right? Like Santa for grown ups. The Problem is: Not all religions are the same. Some are just there, some are bad, some are even dangerous. No amount of people believing will change that.
Good job at totally missing the point. People like you are simply joining the ISIS rethoric of me versus them and are of no use at all.
