Honestly Im not trying to raise a storm, but if you don't know about a religion don't bash it. Im Mormon, I've attended church almost every sunday for as long as I can imagine, in almost every case these missionaries are awkward weird mormons( usually the ones who've been sheltered their whole life) up until their missions, you can use the scriptures to prove really any point, thats why interpretations of literature can be used in many ways. The missionaries ask if the people want to learn the LDS belief, not go into scripture bashing, these kids are normal kids who are 19-21 really how much should they know, they only want to try and bring people into something thats brought them joy, in less then a year I'll be attending a mission of my own. I don't tell people to believe anything I state what I believe, and if someone finds interest I share with them so that they can make decisions for themselves, If you want to find the bad, you can find it in anything, these kids are awkward and not good with people or debate. Yet there are so much more really cool Mormon Missionaries that are doing good things.
Mormons are not a cult, and in fact, if you look up what we strive to do, there is only good things. Again though not everyone is perfect, there are bad mormons just as there are good, it just matters on what your looking for. I myself like to look at the good.
