Why are so many people after mormons!?

What's up with rumors going around that mormons are forming a cult and they're making plans to take over the world..? WHAT THE HECK!?!? So many people are hatin on Mitt Romney just because he's a latter day saint. He'd have so many more people on his side if people didn't care about it. He has some really great things he wants to accomplish, and I really respect him for how he's been taking all this cruelty. Mormons are just like everyone else--the main things done different is swearing and drinking coffee/beer, staying morally clean, or taking drugs/smoking. Some people are like that anyway just because they want to stay clean and healthy. We're jsut like everyone else, and we don't deserve this!! Why don't people go crazy when someone is catholic and runs for pres?? sheesh I just would like to know what's so bad about being a mormon.
