you obviously don't know anything about either religion. mormon gospel focuses on love and happiness, and a kind and loving god, while jehovah's witnesses believe in a strict god and are based almost solely on obedience.
mormons practiced polygamy shortly when the church was first restored - as you probably know, mormons were very persecuted and hated at that time. mobs tried (and often succeeded) to kill or injure them, targeting mostly men (that's how the world worked back then). this caused many widows and fatherless children and during that terrible time men married more than one woman to help provide for and protect them and their children. it's not because they viewed women as objects, like most people think, it was to protect people that needed it.
plus that doesn't help your point, like, at all.
honestly, we are extremely different from jehovah's witnesses, and comparing our religion and theirs shows that you have no idea what you're talking about. so please, before you make assumptions, at least understand what you're saying.
