My own religion
Beliefs don't "need" to be rationally justified, in an ontological or legal sense. Rationality is a feature of accuracy - so if you don't care about your beliefs being accurate, go ahead and be irrational all day long. However, that's not going to serve you well when you try to achieve an objective. If you care about accurately achieving any goal, you should care about being rational.
...
By wrong I meant either irrational and/or contradicted by observed facts. You asked the question, did you have a different definition in mind?
I start at the end, because that is where the meat is. "Observed facts", now the world is not just observed facts, because we have this: Science has limits: A few things that science does not do
Science has limits: A few things that science does not do. The first one - Science doesn't make moral judgments, has to do with observation and not just morality and ethics. It has to do with good and bad in a broad sense.
E.g. I want a good life, I care about that I have a good life.
You can't observe right, wrong, good, bad nor care. You know these concepts based on how you think and feel. And that is not objective nor observable.
Now on to rational as based on or in accordance with reason or logic.
First logic. If you can do either A or B, but not A and B, logic (and reason) only tell you that can't do both A and B. So here are some examples about - "If you care about accurately achieving any goal, you should care about being rational."
- I want to build a bridge over a river. I need to use in short STEM in part.
- I want to kill as many people as possible. I need to use in short STEM in part and find/build an effective virus.
Neither can be done only be wishing for it and I need to employ science in part.
So is rational to want to build a bridge or kill as many humans as possible? No, because the "want" can't be decided using reason or logic only.
Let me explain. We are playing the Is-Ought problem. Both examples are possible as how the world works and you can use science to achieve them. But science, reason, logic, observed facts and so on can't tell you if you ought to do it.
So let me phrase as simple as I can - you can't live only objectively as either with only observation or no personal feelings, prejudices, or interpretations.
The key part is personal interpretation. So back to the big problem in your post:
"However, that's not going to serve you well when you try to achieve an objective." These are the subjective in part - serve you well and having an objective.
Let me explain - if you want a good life (that is an objective) parts of that depend on you subjectively as how you individually are a result of culture, personality, neurological diversity and so on and because you can subjectively can have a good life as you for how you cope, it doesn't that I can do exactly like or nor in reverse.
So the problem with your model is that neither reason, logic and observed facts can do it alone, because if I can cope differently by believing in God, then that is because, it is subjectively well for me and it doesn't have to be so for you.
So here is a version of the at least 4 versions of right and wrong.
Observed facts or objective as of, relating to, or being an object, phenomenon, or condition in the realm of sensible experience independent of individual thought and perceptible by all observers.
Objective as expressing or dealing with facts or conditions as perceived without distortion by personal feelings, prejudices, or interpretations
Inter-subjective as culture, norms, laws, access to technology and so on.
Subjective as how to cope as an individual.
So I am neither right nor wrong, unless you believe that as subjective interpretation, because that, I believe in God, serves me well. The only reason , you think I am wrong, is because you think and feels so.
I accept that you don't believe in religion but you can't use reason, logic and facts to show that it is wrong.
You are trying to do something for which you in the western tradition have over 2000+ years evidence against your idea.
Here it is in one version: "Man is the measure of all things: of the things that are, that they are, of the things that are not, that they are not." - Protagoras.
The key word is measure and refers to subjectivity. In modern terms it is called cultural and neurological diversity.
And you still have to acknowledge this as for observed facts: Science has limits: A few things that science does not do
I am a die hard subjectivist, when it comes to the purpose of life. And I know this, because I am a skeptic, who have tested and doubted reason, logic and facts.
So while we are both parts of the same world, we are different in some cases for what serves us well individually.
As a skeptic concerned with the limits of the usage of reason, logic and/or facts, I can spot the common subjectivity in your kind of thinking and you are not alone. I have been doing this for over 20 years now and you are not the first one, who use this model. And it doesn't work like you think it does, because you overlook the subjective element in human life.
Some people believe they only need faith, And others believe they only need reason, logic and/or facts. I have checked and we all use both. Some people overlook subjectivity in some sense. You appear to be one of them. That doesn't make you neither wrong nor right. It just means that we are different and that is a fact. How you indivudually deal with that is your problem. It becomes my problem, because you claim I ought to be like you. And my answer is: No, I can do it differently, just as you can.
