There is one thing missing from this list that works in some other languages as well: use plurals (groups of people). In general, the words that are used to describe groups are gender-neutral, even when the words to describe the members of the group are not.

Just a simple example. With "nurses" we use "they", "their", "them". With "nurse" you might use "she", "her" and "her", or for a male gender: "he", "his", "him".
