Remember, "he" and "him" are acceptable gender-neutral pronouns and "his" is an acceptable gender-neutral adjective. You don't need to say "he or she", "him or her", "his or her", "they", "them", or "their". Some people (feminists and other idiots) believe that using the male form as default is "prejudiced". It's not- it's just English. These are the same fools who think it's sexist to say "where no man has gone before", having changed it to "where no one has gone before" to placate the gender bigots. Or that "man", the gender-neutral term for humankind, is sexist. In essence, they hate it when males are even perceived to have some role in the accomplishments of the human species, so they need to take the "man" out of "woman" and start calling themselves "womyn".
Using "he", "him", and "his" when a gender-neutral pronoun or adjective is desired is one way you can fight the demonization of all things male.
