Yet, I learned almost all these things in seminary (well, not DNA -- that was recent). And, Deseret Books publishes books on all these topics.
If this stuff is in seminary manuals and in books published by and sold by Deseret Books, what kind of program would you suggest instead?
I, too, have not learned anything "new" from the internet regarding LDS church history, practices, etc., that I didn't already know from reading the History of the Church and other books purchased at Deseret Book. I never bought anything from Signature Books until after I was exposed to anti-Mormon rhetoric on the internet, but the Signatori haven't revealed anything new to me, they just have their particular slant on things.
That said, I know that most LDS don't bother reading anything more demanding than Harry Potter. I know active LDS who believe all kinds of silly things; all kinds of absurd Mormon folklore, faith-promoting stories, etc., etc., etc. And I know many active LDS who are essentially 100% ignorant about the history of the church. And yet, I would estimate that 99% of all the so-called "controversial" topics are referenced, to one degree or another, in the church-published History of the Church, or within the pages of the Ensign. I read all seven volumes of the DHC right after my mission. Great stuff. I loved it. I quickly came to realize that Joseph Smith wasn't the perfect, quasi-mythological character that some like to make him into. That made me like him even more.
I don't know what to say about those who act like the church was "hiding" things from them. I never thought that at all.
One thing I have concluded is that the internet is producing a much more orthodox Latter-day Saint for the future. Yes, there is certainly a movement afoot that is commonly characterized as "New Order Mormons." But I view them as a short-lived phenomenon. Sooner, rather than later, all the NOMs will make the transition to unbeliever. They will not have the stamina to form a viable and continuing movement. But the Latter-day Saint who confronts the easily-obtainable information available on the internet, and who digests it and makes sense of it within the paradigm of his continuing belief, will come out of the process a much more deeply-rooted and orthodox LDS than he was at the start.
