You stated that I had to by necessity be a moral relativist. I do not.
If you are a natural atheist then taking moral realist stance is logically indefensible.
How can an 'objective moral standard' even exist? It is an incoherent concept in and of itself. It is like saying that a favourite colour is objective.
Correct!
And what do you mean by 'subjective gibberish'?
Open a dictionary.
Is this supposed to be some moral justification for fascist dictators controlling other people's lives? They are blameless and free from responsibility as long as they are concise about their rules? What is this?
What is a moral justification in your naturalistic worldview?
So people who stood up against the Nazi's were responsible for the punishments they received? The White Rose Movement knew what they were getting into, so we'll just ignore what happened to them as a consequence shall we?
Jews were simply being targeted in virtue of what they are, not due to any actions or crimes they committed. They had no choice in the matter. There is a fundamental difference between that and, say, being punished due to committing public apostasy in a community where it is illegal. So your Godwin attempt simply fails.
Also from a natural atheistic worldview one cannot morally condemn Nazis. You cannot say that what the Nazis did was morally wrong. That's how ethically impoverished your atheism is.
I'm not specifically interested in explaining how I view morality. I freely assert my moral claims nonetheless with full knowledge of their subjective nature and human-centric objectives. It does not bother me. I tend to think that civilisation and the people in it, if even for reasons of self-interest are valid and mean more than artifical constructs that exist only for themselves and at the expense of others.
Right, so you cannot say that what the Nazis did was objectively wrong. Rape, murder, genocide... there's nothing inherently wrong about any of them in your atheistic worldview.
So all that matters to you here is not whether rules are made in the disinterest of other people's personal liberty but whether they are consistent and concise?
There is no intrusion upon a person's liberty. It is a free choice to be a part of a particular community.
How do you even measure this in a state with unelected leaders? They often (as much as possible) declare rules without asking any citizen of that nation their opinion. They can do what they like for no reason and at the expense of who they like.
It doesn't really matter. As long as they make clear what the laws are and allow the citizens the freedom to leave, a person's liberty is not curtailed.
