It's true that we're learning more about the physical nature of the universe, and that's called science, which the Catholic Church has been a major proponent of all along, as a way to learn more about God's creation.
But the physical nature of the universe is only the physical nature. There is another nature of the universe that is above the physical, and that the physical deviates from sometimes due to the corruption brought into the world by the fall of man.
That "metaphysical" nature is real, even though you can't experiment on it in a lab, and some examples are sexual identity and gender. These are not fluid, even if sometimes the fallen world deviates from it. There are exactly two genders, man and woman, and we are born into those genders, which nobody chooses except God. Sometimes we may have the wrong hormones, but that's part of the fallen nature of the world, and our job is to correct those hormones through science to match our physical gender.
This may seem trivial, but it's a very important example for me because the idea of being a Man and a Woman are very little known or understood by any of us today, whereas centuries ago they were widely understood and accepted, and this plays an integral factor in how I should raise my children as a Father and Man and the Husband of my wife, and the model I should set for these roles, and similarly my wife's roles, what they should be, and the example she ought to give them of a Mother and Wife and Woman.
But when we start to teach young people that these roles or even genders are all social constructs instead of roles built into our very nature which we must recognize and learn how to fulfill, we're soon going to have a chaotic world with everyone doing pretty much everything wrong.
Okay, I see where you're coming from and appreciate you taking the time to clarify.
There is evidence that there has always been a homosexual subset of the population. One can say that this is part of the "fallen" nature of the world, or one can say that this just an aspect of nature based on the makeup of the individual.
Anyhow, I understand where you're coming from, even if it doesn't match my worldview. This is not the kind of thing that one can easily convince another about given that, as you say, "you can't experiment on it in a lab". At a certain point, we do have to take some things on faith.
