See my post #567.
Then you wouldn't be reduced to ridiculous quibbling and niggling and legalizing over who carries more guilt from infidelity, the wife or her cheap paramour.
A man sniffing after another man's wife is attacking a marriage and a family. And in biblical times, he would be hauled out and stoned with the errant woman. In dar-al-Islam, he still would be.
This is like the attitude that priests can't marry but needn't be chaste.
