Public health can't be defended once one commits to abandoning any conception of public morality. The former's dependent upon the latter.
Tolerance of "abnormal" behavior is one thing, but validating it by government decree is to endorse and encourage it. Such actions doom the nation guilty of such broad liberal 'correctness' to that which they have earned,...chaos! Chaos as that society slips further down the road to anarchy, the fruit of the seeds they have sown.
