Basically, I am a live-and-let-live kind of person when it comes to religion. (I admit I fall to pieces over right-wing extremism). I have not found any religion to pass my own smell test. And most, but not all, religions at some point become just another method for exerting power. Or so it seems. And that is where my objections DO surface. It is one thing to accept people who are searching for and/or believing in unproven answers about the infinite, but quite another to be subjugated by them. That I won't tolerate.
And so it has been with me and Mormonism. I've lived in Utah since 1998. In that period of time, I've come to learn some things that the average outsider does not know, because the average outsider's knowledge of Mormonism is generally limited to polygamy and the history of persecution surrounding it. But there is a lot more to it in terms of history, dogma and beliefs that many, many people would find "incredible". In my personal view, this is largely because they are unfamiliar. You know, the Ark filled with pairs of all animals, the talking burning Bush, the parting seas, the Immaculate Conception, the walking on water, the resurrection, these are all fantastical things that do not sound so supernaturally unbelievable to so many people -- despite the fact that we do not now experience anything like these events today. So, I think, the supernatural underpinnings of the Mormon faith only stun people because they are not part of the fabric of the much larger, more familiar Judeo-Christian culture.
