Totalitarian governments need rules of conduct which include moral absolutes just as a free society does. A totalitarian society can no more tolerate stealing, killing, or any other kind of aberrant behavior than can a free society. Less so in fact. This is in addition to methods of control and subjugation used by them.
As for the list of declarationist principles, thanks for them, many or most of them are in keeping with my own beliefs, though they are not, IMO, supportive of your argument that totalitarian government does not require moral absolutes.
The "moral absolutes" of relativists are temporary. They're only "required" until the situation changes. Hahaha
