Those denominations you mentioned, apart from LDS, work from the same source material. They think they worship the same God, and any differences are just how other denominations misinterpret the scriptures or tradition somehow.
You calling LDS a "wacky offering" is directly in-line with my comment and not your objection. Mormons believe they worship the same God as other Christians, but do other Christians really believe they worship the same God as Mormons? You know, the God who sent an angel to give a new testament to Joseph Smith?
