Perhaps some of the LDS here need to look into their hearts and ask themselves that very good question. Especially the ones who keep judging us by what is in OUR hearts.
One big problem that many active LDS people have is that they believe the lie that most people quit the church because they were offended or because they don't want to live the commandments. My own research indicates that this perception is very, very wrong. Most who leave the church do so because they frankly don't believe in the key tenets of the RESTORATION that Joseph Smith was a prophet, the Book of Mormon is true, etc. But alas the believer-LDS keep ignorantly going around telling themselves lies.
