Both historically and currently, one of the top reasons that people have for not liking members of the Church of Jesus Christ of Latter-day Saints (the "Mormon" church) is ignorance. People naturally don't like people that they percieve as 'different' and are generally unwilling to learn more about that person or let them explain why they do or believe that way. People hear rumors about the Church, most of which are false, and form their opinions around these lies.
Historically, Mormons would be run out of town because their population would become so high that the locals would be outnumbered and the politics and culture of their town would change. Now, people don't like Mormons simply because they don't agree with their religious beliefs or moral standards.
Many people remember Mormons for the pioneer trek in the mid-1800's. This has caused some misconceptions of people thinking that Mormons are similar to the Amish, but modern Mormons do not dress like pioneers or travel in horse-drawn wagons.
Well Mormons are very much like the average American. The differences that would separate them are the standards to which Mormons live. An active and rule following Mormon will not have sex before marriage, drink alcohol or coffee, smoke, use drugs, watch 'R' rated movies, or view porn. Mormons live life just like other people: some like football some don't, some like classical music some like rock. They are regular people who are just trying to be the best people they can be.
Uhm...dude, where did you ever get that idea?!?! The Mormons would never kill...people shouldn't spread crap like that :( Everybody was against Mormons
Most people do not hate Mormons, the Osmonds are very popular Mormons singing family. The State of Utah hosted the Winter Olympics a few years ago. Some people do dislike the idea of a man having more than one wife at a time (or the idea of a woman having more than one husband at a time), and some Mormons men have more than one wife. On the whole Mormons who have one spouse at a time are very popular.
Mormons have standards called The Word of Wisdom. Mormons aren't generally prettier than other people. It's just that they don't drink, smoke, or the like. Drinking and smoking are bad for your health and they disfigure the body.
Mormons do not have anything against animals.
Yes, very much so.
You'd have to ask a cannibal, but they likely haven't eaten a Mormon either.
Radical Mormons are people who are Mormons or share similar beliefs with Mormons, but don't fit in with the mainstream Mormon culture. They are either more liberal or more conservative than most Mormons.
No. The Mormons are peaceful people. Why would they need to be investigated? It's like asking if we should investigate Christianity or Judaism or something.
Some Mormons about their own faith, because they are trying to better educate themselves, or see if others think the same way. This does not mean all of the questions about Mormons are asked by Mormons. Also, it is worthy of noting that there are thousands of questions about other religions on this site as well. People are curious, so they ask.
Mormons like their religion because they have strong faith in the beliefs and standards their religion practices. For more information see Mormon.org
