Gender-neutral
Gender-neutral terminology is used by politically correct liberals in a ploy to efface the natural differences between men and women,[1][2] sometimes with absurd effect. Thus, although in legal texts the word "he" and "his" have been used for centuries to apply to both sexes, political correctness advocates insist on the cumbersome "he or she", "his or her". Sometimes people mistakenly use of "they" (or "their") despite the fact that this usage is grammatically incorrect. They also try to abolish terms as policeman, fireman, postman, chairman, actress and waitress, claiming they are sexist terms. Use of gender-neutral language is a hallmark of overly liberal translations of the Bible.
The fact that there are only two genders – male and female, based on one's biological sex – is affirmed through Scripture:
So God created man in his own image, in the image of God he created him; male and female he created them. Genesis 1:27 (ESV)
