Your claim was that 'there needs to be a right or a wrong'. That doesn't allow for a degree of wrongness.
And I have consistently supported that. If you remember I explained objective morality can accommodate circumstances. So the reasoning that was used to find the moral truth in one specific situation cannot be automatically applied to a different moral situation. Each needs to be determined by reasoning.
It's either moral or immoral.
Yes, it either moral or immoral for each moral situation. A moral truth can be found for each moral situation that cannot be made unnecessary by subjective views. Your getting confused I think because you think we can't reason out each moral situation to find the truth rather than slap a truth on the situations ignoring the circumstances.
The reason we can compare at least varying degrees of (severity) of the same moral wrong and to a degree do an overview of morality to see if there are varying degrees of moral wrongness is for the same reason we can reason out the truth of a single moral situation.
Its all premised on being able to look at morality and rationaly and logically determine that some behaviours are better/best than others that will hel humans be humans.
But let's say that you don't know the details. You aren't sure of the outcome. That you don't understand the scenario in enough depth. But you are still saying there is no grey area. It's one or the other.
We may not be able to determine the truth under some situations. You are right there may be some grey areas we are not aware of or don't understand. But this does not mean there is no truth to be found. It may be we find more information, we understand better with time and investigation and we can make a better determination. The point is we act like it matters and that a clear and objective determination needs to happen.
It would be counter intuitive to say Öh well I reckon in my opinion that giving a kid a good beating keeps them in line. We would not want to say "well yeah good for you if thats your opinion". we know that beating a kid is not the best way to behave in how to treat a kid. So therefore we can look at morality and see if there are better/best ways to behave as opposed to other ways to behave.
As opposed to almost everyone else who would say something along the lines of: 'Well, in my opinion, one hour is OK, three hours is probably too long. Five? I personally wouldn't agree to that. But a whole day is definitely too long. And a week is positively criminal'.
Yes people can reason like that. This is exactly what I am saying. But what your not seeing is that when people are argueing whats the better/best time for punishment they are implicitly acknowledging a basis for measuring this. Otherwise what does 1, 3, 5 hours or the whole day even mean if there was no objective basis. They would just be different numbers with no meaning.
So let's skip asking you for a specific time when it becomes immoral. Let's just ask if it's your position that there is some specific moment when it becomes immoral, whatever that moment would be.
Not sure of a specific time as I dont think even medicines that acurrate. But we should be able to determine in each case when it in unfair and unjust to overpunish a child. The point is we know we can get some broad measures of what is better behaviour than others. You acknowledged those, ie 1 hour is better that a whole day.
We could refine that even more with time and understanding. I don't think not knowing all the little grey areas right now means that there is no truth to be found. The fact we can find some better behaviour than others points to moving away from something and towards something else and its not just shots in the dark, feelings, opinions which are arbitrary and too personalise for something so important.
