Sure Christianity has just one god, but there is an awful lot of different versions of him
Are Mormons Christian? They say they are, many other Christians say they are not.

According to the LDS Church, God and Jesus are separate, distinct. Father and Son yes, but in a literal sense, not as distinct manifestations of the same thing. Holy Ghost is a totally distinct entity as well.
Now now, they innovated by turning Facebook from the way you could see what your friends were doing on your feed into algorithmically determining exactly which batshit insane ‘news’ stories from cranks and posts from crazy people would be the most effective rage bait to specifically you once they figured out that anger and rage are the most effective way to cause retention and engagement.
