Ask them why all native americans have the curse of dark skin, if only a small group (relative to the millions of natives already in No. & So. America) of Lamanites were the ones who turned against the Nephites around Guatemala. Why were all punished, even if they lived Alaska or Brazil? Then ask them why native americans all have similar Mongoloian characteristics; why can't you identify Lamanites, because theoretically they should look like middle-easterners with really dark skin and no epicanthic fold. If they say that Lamanites intermarried with natives and their DNA & appearance can't be indentified anymore, ask them what the h*ll difference it makes anyway if native americans have dark skin anyway. Ask them to look for a nickel dropped in the corner of a round room because the prophet Joseph Smith had a revelation that it's there.
