Today, they reject most of the doctrines that you claim are "weird." The Book of Mormon isn't really considered scripture. One of the biggest reasons for the split was the rejection of polygamy - especially by Joseph Smith's wife Emma Smith.

Scripture
Community of Christ points to Jesus Christ as the living Word of God
[25] and affirms the
Bible, along with the
Book of Mormon and the
Doctrine and Covenants as scripture for the church. The Community of Christ view of scripture is that it should be "reasonably interpreted and faithfully applied." Scripture references provided for congregational worship generally follow the
Revised Common Lectionary. The church views the Book of Mormon and the Doctrine and Covenants as "additional witnesses of Christ's ministry and God's love." Community of Christ understands scripture as an inspired record of God's activity with humanity. While it recognizes scripture as the
revelation of God, its members would not typically suggest that scriptures constitute the literal "words of God."

They believe the trinity too!

God, Jesus Christ and the Holy Spirit
Community of Christ states that the "one eternal living God is triune..." and acknowledges God as Creator and Source of love, life, and truth. They state that "God alone is worthy of worship." Jesus Christ is described as both Savior and as a living expression of God and is acknowledged as having lived, died, and been resurrected. As the name of the denomination implies, Jesus Christ is central to their study and worship. Community of Christ's Theology Task Force states that "Jesus Christ is the Word made flesh, both fully human and fully divine."
[13] The Holy Spirit is described as the "continuing presence of God in the world" and as the source of divine inspiration.
