The problem with the kingdom of the cults is semantical. We must precisely define terms, concepts, etc., especially relating to God/Christ. Mormons claim to be Christian because they believe in Christ and use His name in their church title. What they mean by God, Christ, baptism, salvation, etc. is diametrically opposed to, mutually exclusive of biblical, historical, orthodox Christianity. There is one true God, one true Christ. We cannot just accept generic god/jesus/son of God and define these things like our own idol. There are false gospels, false christs (Gal. 1:6-10; 2 Cor. 11:4; Jude 3) that are worthless, non-existent. If one believes Christ is creature, they are denying Him and His true identity. Trusting a counterfeit cannot save. Trusting the Jesus of Islam cannot save you. Denying His Deity is denying Him and not honoring the Father. You wrongly assume that we cannot know whether Christ is God or creature. He does not leave this option. He is Lord God as claimed, not liar, not legend, not lunatic, not Michael the Archangel, not one of many LDS gods. Likewise, we cannot trust Islamic Allah and think we are trusting YHWH of Judeo-Christianity. We cannot trust the New Age Jesus Son of God since it is a demonic counterfeit. Many pseudo-Christian cults believe in the Son of God, but really do not know Him because they deny the most basic truths about Him. Likewise, some believe in Jesus, but deny His resurrection. Paul said that this is a denial of the gospel that saves us (I Cor. 15). We cannot water down the gospel and sound doctrine of God to make it palatable or more broad than God intended. We must look at the evidence and decide whether we are to worship Jesus as God or honor him as God's creation. Both are not equally true and not equally salvific. Either WT, LDS, Protestants, Muslims, etc. are right. We cannot all be right with such differing views on basic things.
