Can we agree that every govt legislates morality? Every law is a reflection of some moral. Our laws against murder are based on the fact that we think it is immoral to take innocent life. Our laws against theft are legislating morality. We all hold stealing to be immoral and our laws against theft are based on that moral.
So it is not a question of whether we are going to legislate morality but whose morality are we going to legislate. yes?
Are we going to legislate biblical morality? Buddhist morality? secularist morality? etc.
