We are not literally calling anyone a 'gentile'.
Define "literally" please.
I see the misuse of the word "Gentile" by Mormons on this board quite often, and the author of this article even uses it.
Moreover, I can find it Mormon literature and atricles all over the net.
Since antiquity, the correct use of that term is to describe non-Jewish persons and non-Jewish nations.
Your posting to me sounded like "It depends on what the definition of 'is' is."
