Yes, that is the reaction I get from some people when they learn that I am a member of the Church of Jesus Christ of Latter Day Saints (the Mormons). Others rely on rumors they have heard, or false information that is often shared about the Mormons by folks who haven't even checked it out for themselves to be sure their information is right.
If you wonder what being a Mormon means, you can find that information here: http://www.mormonnewsroom.org/article/mormonism-101
It is bound to answer a lot of questions you may have.
