Does Wyatt not have Peterson's mobile number? Email? WhatsApp? Why post such a personal message to someone with whom you have close contact, in the comments section of their public blog? Is he trying to tell everyone that he and Dan are friends to gain some perceived kudos or oneupmanship? Did Peterson not send a "Happy New Year" message to all involved at Interpreter? Did he do just that but miss Allen off?
Premise 1. Eyewitness testimony is notoriously unreliable.
Premise 2. The best evidence for the Book of Mormon is eyewitness testimony.
Conclusion. Therefore, the best evidence for the Book of Mormon is notoriously unreliable.
I regularly wish people happy holidays and such on public platforms, even when I have their personal contact information. I didn't know that was a weird thing to do.
