Mormons can have their own religion, they are free to do what they want.  

The objection I have is the clever and obnoxious ruse they used by putting "Christ" in the name.  

They used the name and some traditions,then built a completely different doctrine around it. Man as ascending God.  They don't encourage their people to spend a lot of time on doctrine issues.  They do encourage them to be good people.  

The entire idea that God was a man who somehow became a god and that it is every saints goal to do the same is non-christian.  The idea that you will end up ruling a planet surrounded by your wives and progeny is non-christian.  Just by definition they aren't christian. Its not a right or wrong thing, it's just what it is.

Mormonism is the Scientology of the 1800s.
