Mormonism rejects the Trinity and you get your own magical planet/become like God when you die. I think most Christians would find that profoundly heretical.

The church has mostly been doing a propaganda campaign to present themselves as just another denomination of Christianity, but Adam-God and the spirit wives is just gross and weird.

“Hey ladies! The best afterlife you get is pumping out babies with all of your husbands other wives for all of eternity!”
