Mormons the Israelites

Here's an early doubt for you. According to the Book of Mormon, Joseph Smith was a direct descendant of Joseph, the youngest son of Jacob who was sold into Egypt, and Brigham Young confirmed that our latter-day Joseph was "pure Ephraimite." This might lead one to believe that the British Isles were populated by the tribe of Ephraim, right? The Brits must be Hebrew at heart.

But they're not. Neither was the Smith family. The Book of Mormon prophesy was bullshit. DNA evidence proves that.

"Gryffindor! No, WAIT... Ephraim!!"

And yet Mormons continue to claim lineage to the tribe of Ephraim. Isn't that a bit arrogant? How do Mormons expect anyone to take them seriously when they start spouting off about being Ephraimite? Just don't get your hopes up for an Israeli duel citizenship.
