Here are some distinctions that are relevant to the permissibility of Roy Moore's behavior:
- Dating, courtship, sex, and marriage.
- Sex and rape.
- Rape and statutory rape.
- Law, custom, and morality.
- What the law is and what the law should be.
- What the law was and what the law is.
- What the moral norms are and what the moral norms should be.
- What the moral norms were and what the moral norms are.
- Whether moral norms are absolute or defeasible.
- Whether moral norms are universal or relative (to times, places, &c.).
By the way, I wrote the book (literally) on rape. Two of them, actually, plus many articles in prominent philosophical publications.
