I've been reading a book filled with research about the lost civilization of Lemuria. Apparently, there used to be a race of long-eared people. Now, Lemuria sunk millenia ago, but descendants of this long-eared race supposedly still live on this planet. Imagine if I wrote a story about Lemuria. Now, let's say I claimed that the long-eared race had actually migrated to an alien planet. However, they were evil and plotted to take over the earth. Wouldn't I be offending the descendants of this race? I'm sure many of you have stumble upon this issue before. What would be your approach? Many thanks.
