Full Idea
A moral tradition need not be committed to monogamy, but it must regulate sexual conduct to prevent inbreeding, protect the sexually immature, prohibit some forms of coercion, and assign responsibility for raising children.
Gist of Idea
Sexual morality doesn't require monogamy, but it needs a group of sensible regulations
