All legislation is legislated morality. Morality really means a rough consensus of what a society considers right and wrong--it changes over time. Once upon a time women baring their ankles or legs or wearing makeup was considered immoral and only a prostitute would THINK of doing such a thing. Walk into almost any church and you'll see makeup and knee-length skirts. Some women will wear hose and some will not--actual bare legs. Immoral! Morality is mutable, but virtue is not; a woman wearing a knee-length skirt and too much makeup, or even (Heaven forfend!) a bikini, may be completely chaste. The morality provides at most a clue to the underlying virtue. VIRTUE cannot be legislated, it must be freely chosen.
