By your definition than, all religions are cults - it had to start somewhere, with someone.  The practice of polygamy was done for many reasons, none of which are the sick, twisted reasons in your mind.  See how far back and who exactly practiced polygamy and I'm sure you'd be enlightened to know that it happened way before the church was organized.  You probably even have ancestors who practiced polygamy.    The church did not rewrite, or translate, the bible to suit their own needs.  The church uses the widely used KJV version.  Every other version has been rewritten to suit the needs of the interpreter.  Charles Manson and David Koresh did reprehensible things to people.  Please site examples of what the Mormons have done that are similar to the aforementioned.  You have no idea how much good the Mormons have done in the world.
