Ok - here :S
Everyone knows why they are right, everyone knows what proves their viewpoint, a particular problem of faith based beliefs however, is that very few know what would disprove that belief.
As a mormon I loved the church, it was fantastic. I was glad that I had a progressive worldview that was welcoming of science (indeed welcoming of all truth) and instead of feeling threatened by the success of other churches, worldviews or non-mormons I, and my church, had a very broad view (god gives light and knowledge to all his children.) To be a mormon was not to take away from others beliefs, it was to offer them additional info they hadn't come across before. As a missionary I wasn't converting people away from say catholicism I was acknowledging how important that organisation had been as a way for god to teach them things and was offering them the next stage, I offerred Catholicism upgraded, Bhuddism upgraded, Humanism upgraded etc. All along I welcomed information because I was so certain that we had the facts, we had real truth , we had an actual prophet and this was the only church actually managed and set up directly by Jesus.
That which I described above is what brainwashing does. From my earliest memory I was singing 'Follow the Prophet', I was given 'historical' reading books on the Book of Mormon,I was attending impresive media productions on South American archaelogy that proved the BoM and so on. I didn't so much as find my testimony (though at 14 I did have an incredible experience) as have it layered into my psyche day in and day out. My weekly schedule (prior to the consolidated meeting schedule) was :
Sunday morning Sacrament meeting, meal at church or church members house, Sunday Afternoon Priesthood/relief Society Meetings, Sunday Evening Fireside, Monday night Family Home Evening (Lesson, songs and - normally edible - treat) , Tuesday Adults meetings at church for various auxiliaries (so Mum was on Young Women's Presidency so I ended up wandering church corridors), Wednesday MIA (church members mixed adults and kids activity night), Thursday night Sunday School, Friday night church sports / fireside / special activity, Saturday infrequent Stake/ Regional activities like sports events, Roadshows, Bring and Buy sales etc. In short my entire life outside of school was church related. Don't get me wrong, I loved it, but I was not exposed to any other influences nor was I ever taught how to think, everything was a black and white absolute of what to think.
The bookshelves of our home were loaded with church materials, my weekly 'comic' was the church publication 'The Friend' and then as I got older 'The New Era' filled with faith promoting stories, puzzles about the BoM and information on prominent church members or high achievers. On top of that we had missionaries over at our house regularly for meals and to teach people (female missionaries, my mum was single so males not allowed!)
This is what brainwashing is, this is what a cult does, this is what makes it so hard to freely think and evaluate. I have pondered long and hard about why I didn't see the problems, why I couldn't perceive the logical mistakes. The only conclusion I have is brainwashing. A person wearing blue shade glasses indeed sees the world as blue but the glasses must be removed in order to see that the world isn't all blue. I had to take off the glasses before I could recognise that the church was NOT true. Until that time every tiny bit of information (like that presented by Cold Steel) seemed like the most incredible proof and every negative bit of information was brushed aside with barely a flicker of recognition.
Only when you know what would invalidate your belief are you able to evaluate it - otherwise you are simply rote learning.
* No miracle stories of Mormonism happened as described in church lesson literature (Checked with primary sources.)
* No prophecies of Mormonism with general application have ever happened (Check them all!). Many personal prophecies were either easily fulfilled (you will go on a mission - said by the person who can send them on one - or you will have a child (doh - most people do) and so on) or simply forgotten and brushed aside when they didn't occur.
* No archaeology agrees with Mormon claims and almost all directly contradicts it (DNA proves no American Indian ancestry from Middle East, no animals of types mentioned in BoM native to Americas, No evidence of million man battles or sprawling huge civilisations matching BoM civilisations, flora and fauna not native to SA mentioned, native flora and fauna not mentioned and incorrect or anachronous technology such as glass windows, chariots, steel, concrete, silk etc.
* BoM contains various source material available to Joseph Smith and indicating human origin (Map of Cumoros Island with capital Moroni - key names in BoM, many names of places lifted from local towns, Indian place names and geographical regions, Swedenborgian spiritual philosophy, superstition and magic elements - treasure digging, seerstones, divining rods, rituals to collect buried artefacts, masonry, direct lifts from several books of the day (I can provide several hundred direct and paraphrased quotes from books of the day if needed - mind boggling) most notably the bible (lifts including known errors and puzzlingly things he corrected in his later bible 'translation'.)
* Joseph made several translation claims that failed (Greek Psalter, Kinderhook Plates and now we have a fragment of the original Book of Abraham papyrus, the Book of Abraham)
* Joseph committed several horrendous social abuses (cornering married and single women in back rooms, telling them that an angel had commanded them to marry him, if they would submit they and several generations would be guaranteed Celestialisation and if they rejected him they and those same generations would damned ), he had an affair with a 14 year old (culturally not that 'bad' but still unacceptable), he set himself up as the seller of property in each new territory he founded (so he always could make money), he set up a fraudulent bank and fleeced many members (the primary reason for a vast apostacy in the early days of the church), he made up doctrine on the fly to suit (Word of Wisdom to placate his wife and containing the instruction to drink beer but not spirits - unlike our latest incarnation of it, Celestial marriage and the whole temple to hide his affairs and so on.)
In the broad light of day only brainwashing can lead a sane, rational adult to accept this whole rotten lie. Even though the modern day church is very different now its history is mired in awfulness (Utah under Brigham Young was a terrible place where people disappeared, women lived under absolute male rule, polgamy plagued the people and saw old men picking and choosing young wives at will, castrations of men who wouldn't give up wives etc.) No matter how many flashy ads the LDS church puts out it will not beat its history and the internet.
