Either way, there isn't any Nephite or Lamanite DNA to be found anywhere. So the political designations made by Moroni don't have any impact on the Lamanite/DNA question, since according to the Book of Mormon they're all descendants of Lehi, be they Amulonites, Amlicites, Josephites, Jacobites, Nephites, Lamanites, King-Men, Gadianton Robbers, or what-have-you. (emphasis added)
You mean, according to your biased interpretation of the Book of Mormon. The Book of Mormon never says that all these people are descendants of Lehi, and in many instances, seems to implicitly suggest otherwise.
Of course, you know that. We've been over this ground many times. And there's no point in going there again.
As Mormons, much of your belief system was based on false assumptions. And ironically, as ex-Mormons, you feel compelled to continue to defend those false assumptions.
