Question 9: Is this about men/women generally or husbands/wives specifically?

Greek uses the same word (gyne) for woman and wife, same word (aner) for man and husband. Pro-woman: v.12 (man comes from woman via birth, not marriage), and man/woman are used broadly by default. Pro-wife: woman as 'glory of man' especially suits marriage, Adam/Eve are married, Ephesians 5 makes headship a husband-wife matter (singular). Mike's middle ground: primarily about marriage but applies as a general rule because marriage is normative -- the headship principle is broadly true but most manifestly applicable in marriage.
