What you quoted was not preached from the pulpit by an LDS prophet. It was written for a Wikipedia article, summarizing SOME people's opinions of what was taught. But not the LDS church's. By contrast I suspect the typical LDS view (among those who even know what you're talking about; most probably do not) is given later in the article given by Pres. Kimball, "[Pres. Kimball] said that he did not say that President Brigham Young did not make the statements which are attributed to him, nor did he claim that they were falsely reported. Neither did he say that Brigham Young taught false doctrine. What he did say and what he meant is that the Adam–God theory is false, and the Adam–God theory is that interpretation which is placed on Brigham Young's words by present day apostates and fundamentalists—their understanding of what Brigham Young meant is false."
If you want to have a serious discussion about the Adam-God theory, then read the original sermons by Young as I have. Then you can read the analysis of them that I wrote several years ago, here.
https://www.physics.byu.edu/faculty/colton/personal/lds/adamisgod.htm (I've actually included many paragraphs of the original sermons in case you don't have a source for them.) Then we can talk.
But doing a "drive by posting" of a Wikipedia article implying that that's what LDS people believe (especially when you even admit that you know we don't believe it!) is just lame. Hence the neg rep.
I don't follow the logic.
