Unfortunately for this idea, there simply are things that no one can reasonably deny or call "red" when it is demonstrably "green." For example, take gravitational pull.
Of course there are stable systems in nature everyone, regardless of their language recognize as real. How they understand what that is however, is not the same, nor absolute. There is the mythic understanding of gravity, and there is the magic understanding, and there is the scientific understanding, etc.
But as a note of caution, just because you can identify stable systems like physics, that in no way translates into all the rest of reality being reduced down to an understanding of physics only. That's a perceptual absolutism; 'the scientific view of reality is the only truth'. And when you do that, you shut the door on understanding. It's doing the same thing as saying, "God said it, I believe it, that settles it for me".
Do any of us get to change our "lens" on gravity such that what we experience is different from what others experience? When I go to use the (estimated) value for gravity on Earth to estimate where a ball might be after 5 seconds of falling, can someone else use a different value and make as accurate a prediction as I can? No. No they couldn't.
There's really not much need for that. But is life and understanding reality as basic as gravity or the orbits of the planets? I heard someone musing, "Science can tell me with precise detail where a moon of Jupiter will be 1000 years from now, but they can't tell me where my dog will be 10 minutes from now." Reality is far more complex and nuanced and subtle than the orbits of moons and the speeds which objects fall on earth.
And that's just an extreme example. Certain qualia is experienced differently by different individuals. For example, my hands happen to be extremely heat resistant. To the point that I can deal with holding hot plates and rinsing dishes in scalding water, and even don't suffer burns at temperatures another people's skin would burn when exposed to. However - NONE of that changes the ACTUAL temperature of any given object either one of us might come in contact with, and we can literally verify what that temperature is with instrumentation. THAT'S exactly the kind of "sharing" I am talking about. Not when one person says "this plate is hot" and I say, "Oh, don't worry about it, I can take it." That difference is understood, but DOES NOT change the fundamental reality of how hot the plate actually is.
Again, you are looking at the world through the scientific lens of reality. Yes, of course there are truths found within it, to be certain. But we aren't talking about skin sensitivity to heat, or muscle strengths, and really elementary, basic things like that. Just because the tools of science can be used to examine these, does not translate into it being the right tool to understand what reality for those who live in the world. That understanding of reality, is like saying, "only what I can physically touch is real." Do you believe that is true?
Humans develop languages to try to talk about the experience of being, the experience of existence, the experience of others and the outside world, and the experience of themselves. These are all subjective realities. And the language of science, talking about gravity and and skin responses, does not begin to approach any of that. It's like try to use a calculator to express your love with, or to answer questions like "Why do I exist". While that may be satisfying to a rare few, most humans don't experience life like that, and the calculator answer is seen as insufficient as Noah's magical ark story is to the scientist looking to understand speciation.
And what I am saying is that all I really care about is how hot the plate actually is.
If that's all it takes for you to find truth, meaning, and purpose in the world, then yeah, you have no use for any of the bigger questions of life, which religions attempt to address in their various filters or lenses they use, from magic, to mythic, to rational, to holistic, to mystical or transcendent. You find the materialist, physicalist lens of reality to be sufficient, apparently. But it does beg the question then, why you are on a religious forum which is all about these larger questions, if how hot the plate is is all that matters?
This, alone, makes all this garbage COMPLETELY different than something like gravity, or the heat of an object, etc. It is entirely subjective.
Everything has subjectivity as part of our understanding, including "objectivity". It is inescapable. We are subjective beings in our very nature, and if we try to get rid of that in a quest for objectivity, that action itself has subjectivity as its base. The subjective desire to be objective, is a subjective desire.
But to your point, and mine as well, what your objection as well as mine is, that when someone tries to say that their view of God, or Reality, is absolute, objectively true. That is a true for the mythic-literal view of reality, or the scientific view of reality. I don't believe even science itself ever claims it is the final arbiter of truth on reality. Those who seem to think it is, I see has suffering from a bad hangover from religious literalism.
As a funny story, a friend of mine who like myself became an atheist after our Bible College days, said to me, "I'm so glad I know the truth now!". I said to him half joking, I remember you saying that same thing when you were in class with me. He paused, then responded, "But the difference is, now I really DO have the truth". You see my point? It's treating scientific views, as a replacement for religious authority.
Entirely so, without a single speck of objectivity attached to it. It is of your mind... and yet you are loathe to admit it. Why is that?
Are you asking that to a generic apologist, or to me? This certainly doesn't reflect any way that I think about these things. I see God as Reality, that which is Real, with a capital R. The religious perspective, and the scientific perspective, the magic perspective, etc., are all perspectives on something wholly beyond our abilities to comprehend.
All perspectives are relative. They contain partial truths, not absolute understanding. Anything the mind does, to think or conceptualize anything at all, is not absolute reality. It can't be, because the mind is not the measure of all things. It's just a limited, albeight effective tool at doing certain things. But it's like your right arm, is not the whole body.
When I eat a particular flavor of ice cream and state that I like it, and you eat the same and say that you don't like it, do I try to convince you that you are wrong? Or do I start to talk about how your "filter of reality" must be different than my own?
That would have nothing to do with what I am talking about with filters of reality. I am referring to collective systems of language and symbols that members of a group all use to speak to themselves and each other through. Those structure, those frameworks, are collectively used. And if you don't use those yourself, you will see things differently than those in the group who do.
