Religion and government have been arbiters of what is permissible between people since the dawn of humankind. Societies have different standards on the same issue. Look at the age of consent for sexual relations. Angola’s age of consent is 12. China it’s 14. In the US it’s anywhere from 16 to 18 depending on the state.
Issues around sex could use the same open airing as LGBT issues have had. Our politics should be about the policy and not the policy-maker. Naïve? Probably. Likely to change? Not any time soon. Puritan sex wins.
