Is it just me or is "woman director" strange grammar? Why not "female director"? "Woman" is a noun. Would you say "man director"? Or, "I work for a man boss"... ?
Fighting the good fight. “Woman” is no more an adjective than “man” is, and no, people don’t write it that way because of the relatively new incel phenomenon. They write it that way because they’re using the word incorrectly.
