The college writing handbook I have right here on my desk specifically prohibits "mankind" as exclusive, rather than inclusive, language.
Then you have a poor handbook in front of you, written by the sort of people whose advice in such matters should generally be ignored.
Whatever your feelings about that might be, Sean, times have changed and so have expectations. Today's students are expected to use gender inclusive language, including the use of "people" or "humankind" rather than "mankind."
Not entirely, or the student wouldn't have used the term, nor I defended it. Most dictionaries do not yet accept the distinction you or your handbook makes. Nor do people who know how the language evolved. As I pointed out, mankind
is gender inclusive. It always has been, and was long before "man" also began to be used as a gender specific term. I suspect that, like most forms of political correctness, this is a linguistic change that will never wholly catch on, beyond certain ideological pockets of society.
On a tangent . . . do other languages have the issue of gender inclusiveness?
Not really. That sort of nonsense is possible in English, largely because gender has already mostly disappeared (it used to be a gendered language, too). As a result, English speakers can think that having a masculine noun for the species is sexist. They are still wrong, but at least it makes a certain amount of sense, if you don't know the history of the language. In a gendered language (which includes most of the Romance and Germanic languages), this sort of thing doesn't gain traction, because it is obvious that gendered nouns have nothing to do with actual gender in the real world. The issue in English occurs therefore out of ignorance, as I said before, and the sensibilities of ignorant people should not concern any writer who is not specifically writing for an ignorant audience. As you point out though, some university-level writing will fall into this category, and then one must bow to the dictates of political correctness.
