If you are not in contact with the spiritual along with the physical, you will never come close to understanding this world or God or the Bible or human beings, or anything, really.
I've explained to you before why I believe it. If you don't get it, you aren't really doing any homework or bible study with an open-mind, at all. If you can be open-minded about gender fluidity, why can't you be open-minded when studying the Bible? Is it because you'd be faced with the fact that all of us are flawed and we need God? If you don't like the idea of needing God, then you need some humility because like it or not, we all need Him. And, he responds to a contrite, humble heart, not one filled with arrogance and haughty pride.
And of course because He made us all male or female, you are faced with His displeasure at this "gender fluidity" agenda, which is now affecting children.
