I expect on one level you're right but I also think that it's because they don't want anyone other than government (themselves) to arbitrate right and wrong.
It never ceases to floor me when I start a secular humanists talking about how one knows the difference between right and wrong. They are absolutely stupid on the issue and you'll see a lot of it on exhibit in the comments on the Hume/Woods story.
There are no absolutes in a secular humanist’s world, only gray areas, ill defined outlines of human behavior, and fuzzy feel good morality rules. “Who’s to say what’s right or wrong?” “If it feels good, do it!” “All cultures are equal.” “Diversity is strength.”.............
