Your point on Christian behavior not defining a Christian is a point I’ve tried to make. We do agree there
I think we may have to agree to disagree on the second point. You and I may not be so far apart on our faith traditions view of Jesus Christ as many Protestant faith traditions are not very different from a Catholic view of Jesus. The LDS, however, are so outside the box in their true identification of Jesus they can not be called Christ followers. Do they follow a “Christ”? Yes, Joseph Smith’s version of a christ is very far from the Christ Christians follow.
In recent years, say the last 20-30 or so, the LDS have worked very hard to be seen similar to mainstream protestant faiths. As the information age has come to fruition and the truth can be found easily the LDS have had to make adjustments, developing doctrine so to speak. It’s somewhat difficult to find the actual meat of their theology when doing a simple online search. Mainly you find these superficial pieces filled with fluff about who & what they are.

*God, the Heavenly Father - Mormonism is unique, however, in its belief that God has a physical body.
Jesus Christ - Mormons do not agree with mainstream Christians that Jesus is the eternal Word of God or God himself.
Holy Spirit - Mormonism departs from mainstream Christianity in teaching that the Holy Spirit is a “one in purpose with the Father and the Son, but is a separate being” rather than an aspect of God or part of a Trinity.*
