The staff at BOMC are great people. I agree they are wearing the Mesoamerican lenses, but let's be patient. Give them some time. Encourage them to take off the lenses if you get a chance. Maybe, eventually, they'll follow the Church's official policy of neutrality and at least allow presentation of alternative perspectives on a fair, concurrent basis.
Meanwhile, I'll try to comment when they miss really big opportunities such as this one. Let me know when you see something you want to discuss, as well.
I'm still optimistic that someday, they'll realize we all share the same belief in the Book of Mormon and the same objectives in sharing its message. Along with that, I hope they'll realize there should be room at the table for faithful LDS who don't accept the Mesoamerican setting.
All we can do is keep trying.
