Thats right morality is not determined the same way as science determines facts. BUt it works the same way inthat moral truths are facts like in Math which also cannot be verified through scientific tests. When someone says "Rape is wrong" that is stating a moral truth that the act of rape is objectively wrong.
No if you make an objective statement the truth of this has to be beyond the subject. Otherwise they are just make any statement. Otherwise about the subjects state of mind and nothing actually beyond the mind that is a fact. So when you say 2+2=4 its an objective fact beyond the subject. We can know by looking at the equation that is adds up correctly.
But if someone said 2+2=5 we can say this is not objective beyond the subject but rathe rits just how the subject personally views things. It may be an objective truth for the subject but its not an objective truth beyond the subject.
Like I said objective morality has no scientific test to prove it. It is like a law of nature, just like Maths is a law or fact. We know moral laws just like we know Math laws. 2+2=4 is the same as rape = moral wrong. Saying rape is morall good is like saying 2+2+5.
I have given this information many times. I just did it again above. Thats all there is and if your waiting for some lab test verfication its not going to happen. But we can look at human behaviour as I have mentioned and see that moral language is like Math, and is about facts.
Your right that science is about desriotive statements and morality is prescriptive. Moral norms are a good example of prescriptive language that is about "Oughts". You "ought not rape" for example.
No it would be like a Star Wars fan raving on about how "Star Wars is the best movie ever" and someone saying but thats just your opinion. It doesnt mean Star Wars is actually the best movie ever. Thats why I keep saying your examples of subjective preferences for TV shows doesnt work for moral situations. If someone said Star Wars is full of space ships then this is an objective claim. JUst like someone says "Rape is wrong".
But how do people reach that agreement. How do they determine that which is agreed on is the best way to go. When people do disagree what are they disagreeing over and how do they sort out that disagreement.
There is also no complete agreement about scientific objectives. But when agreement is reached it is complete agreement that there is an objective. When people agree on a moral value they obviously have a shared basis like say rape is wrong because it harms women. If someone subjectively disagrees they are just mistaken just like they would be mistaken of they disagreed that 2+2=4.
But its not and I keep showing you how its not. How we act and converse with preferences for TV shows is descriptive (it describes something about the subject. Morality is different as its prescriptive. It tells us how something is outside the subject. How the act of "Rape" is wrong beyond the subjects preferences. Just like the Math equation 2+2-4 tells us a fact beyond the subjects personal view that 2+2=5.
I am only explaining the difference in how morality works compared to subjective thinking. Lets just get how morality works right first.
Its funny when I explain thiongs logically rather than address this you fall back on saying it all doesnt matter as I haven't proved objective morality to your satification. What I am explaining is the support for objective morality. EXplaining that we don't act or converse like morals are subjective is part of the support which you keep fobbing off.
I'm not saying that. I am asking So do people’s preferences for TV shows have equal status in the world as yours even if they have the opposite view ie (they like Star Wars and not Star Trek).
But when people march and protest these morals they are not some new subjective moral view they want to impose on others. When people protest about the treatment of women as we have seen with the "Me To" movement or above domestic violence or about BLM these are already established moral truths.
People are just making it known that these moral truths are basic natural rights that we all agree should be upheld. BUt this doesnt happen with preferences for TV shows. We don't march in the streets or sack people for preferening Star Wars. So what I am saying is that people do treat moral issues differently to subjective thinking.
So therefore if a person had the subjective view that rape is morally ok where do they stand.
No I am using logic. I am questioning how we determine moral judgements. Is it best to use subjective thinking or objective thinking when making moral decisions about what is right or wrong.
I am questioning whether subjective thinking is the right way to determine such important matters that need to be correctly decides as to what is the better/best moral behaviour. Like I said I am now trying to breakdown how subjective and objective morality works.
Yes thats what Ive been trying to point out. This is what moral realism is about. That we converse and act/react as though morals are laws like in nature. Just like we do with the physical world. What we think in our imagination which is subjective thinking is not how morality works in reality. A person can say I think stealing is relative to the situation but when they have something stolen from them they act live stealing is a moral truth and is wrong regardles of relativity.
And before you say "just because people converse and act like there are moral truths doesnt mean there are moral truths". As pointed out above that everything you said regarding "who to kill" in your moral scenario implied an objective basis for measuring how to determine what is the best way to act morally.
So its not just because we act/converse like something therefore its true. For morality acting & conversing is what makes it real and truth. There is no alternative way to act or speak in these matters because we know that moral matters need a truth.
That is moral realism in that it claims ethical sentences express moral propositions that refer to objective features of the world (that is, features independent of subjective opinion), some of which may be true to the extent that they report those features accurately. That is what I have been trying to explain to you and others.

If you base your decision on an objective fact then it cannot be subjective thinking. As soon as you appeal to some objective outside your subjective mind/thinking as the measuring stick for your decision you give you subjective thinking. We can then point to that fact outside the subject and say this is the truth and any personal opinion is wrong factually.
That is why I am pointing out that we cannot help but use objective reasoning/language for moral issues as you have just demonstrated in that you acknowledged that we need some fact to base moral decisions on and not subjective opinions.
