I just so happen to be a church going kind of guy. I'm also the kind of guy who listens a whole lot more than I talk. Over all of those years of being around Christians of all stripes and listening to them whether I'm being addressed directly or I coincidently overhear, generally speaking, the quietly spoken and unmentioned jibber jabber that outsiders never hear is the criticism the Mormons get whenever they become a topic of discussion amongst a group of trusted congregation members and the like. I won't get into specifics, but the comments are usually negative in nature. Many of the fundies I talk with or overhear are usually the most outspoken and critical of the Mormons and they aren't modest about the topic either.
This is the knowledge I based my opinion on.
I have my own personal opinion about the Mormon Church, but for me, it's personal and not subject to discussion with others. However, I can say that I have Mormon friends who I admire and respect and do not hold their religion against them in any way, shape or form and they feel the same way about me.
