Mostly it is mormons complaining. No one else thinks they are christians. It is a stolen valor thing. They want the respectability of being called Christian without having to believe anything that christians believe. As a Catholic, that is kind of how I feel about Nicean Christians who want to redefine what Catholic means in the creed so they can still claim it. That being said. I do actually consider most to be Christian because they have baptism and what baptism does is make someone into a Christian. Thus they are part of the church whether they like it or not.
