The definition of Christian is "one who believes in Christ" I'm aware that Christians don't want Mormons to be part of their in group, but they do believe in Christ and the Bible, so if you want them out you would have to change the fundamental definition of "Christianity". It's wild how many people don't understand the fundamental definitions of words that we all agree to use. I'm literally not asserting anything except that they believe in Christ, and religious people want to freak out about it and say no they don't? Great example of how religion is pernicious and divisive.
