Alas we can not rename categories, I would say best to make a new category and name it Inuits then shift all the pages there and delete the original but fact is we are trying to phase out the nationality pages all together. If you like I can delete the category all together but replacing it with an Inuits would only create more work for us later. Let me know if you would like me to do so and I will make it a priority.
Yes, I and admin Garfield1601 have been trying to clean up the junk categories and one of the factors we have been trying to focus on are nationality categories. Basicly the thought is being from a certain country or of a certain nationality does not having anything to do with one's heroics, nor should it. There are quite a few, pages are constantly re-added and there is much other work to be done cleaning up the wiki but Nationality is still being phased out in between other category clears. If the term Eskimo is offensive I will makie clearing that one top priority but I can not replace it with another one at this time.
