Rationality is based on facts. What you and I accept as fact maybe different. I can't force you to accept something as fact regardless of how firmly I belief it is a fact. And vice versa, therefore what we accept as rational may not be the same.
Facts aren't based on what you accept but on what is actually true. Whether you accept it or not is entirely irrelevant. Someone can believe the speed of light is 47mph. They're just wrong. It isn't a fact in any way, shape or form, no matter how much they wish it was so. Rationality is indeed based on facts. Just believing something doesn't make it a fact, any more than rejecting something makes it not a fact.
All based on what I have decided were the facts of my experiences.
Your opinions about your experiences, you mean. It's only when you can demonstrate that your experiences actually happened as you believe they did that it becomes a fact.
But that is what humans do. That is all we do. Attach significance to our experiences. I see this and understand this and realize how arbitrary it all is. Man creates the knowledge, defines the knowledge and determines what the facts are. We did this with God and now do the same with objective reality.
Just because people do it doesn't mean it's the rational thing to do. People attach irrational and factually incorrect significance to their experiences, we both agree with that. The only way for these things to be rational is for them not to do so. People doing something irrational doesn't suddenly become rational because everyone is doing it.
You decide what matters. you can decide it for yourself. You can't decide it for me.
I'm not trying to. What is important to you has no bearing on what is objectively rational though.
Lets say there is a God sense. You don't have it, someone else does. For example Christians claim the Holy Spirit is their God sense. Someone with out this sense would conclude there is no God and they would be incorrect. It is only through further evaluation we can come closer to the truth.
But that's just something that you pulled out of thin air, it isn't demonstrated. Let me know when this "God sense" has actually been shown to be real, until then I'm not going to play hypotheticals.
We are not capable of observing objective reality, we can't experience it. There exists no objective proof for it. Yet you insist it exists. The only thing we know is subjective reality based on our own experiences.
Perfectly? Probably not. We can work to come closer and closer to observing objective reality though. We can understand our own shortcomings and work to overcome them as best we can. That's what science does. There are reasons we have to think critically about our experiences so we can accept those things that are objectively best supported and reject those things that are not, thereby getting closer to reality. If you want to live in a self-imposed fantasy land, feel free, certainly nobody can stop you, but you're not rational when you do so.
