such as like this:
The concept of gender identity is said to be real as an experience, (like how theists claim to see god [a claim basically]), but scientifically under-defined, weakly grounded biologically, and sometimes treated as more fixed or explanatory than current evidence justifies.


You mean from fallacy
False dichotomy, it could be a third thing. Also the idea that “socially constructed” things are somehow unworthy of consideration, or irrelevant is not true. Consider some things that we know are “man-made”: sovereignty, laws, borders, language, authority, religion, democracy, human-rights, and class. Think those things are “irrelevant”?
I mean as opposed to ideological reasoning. Natural reasoning is a conclusion that I can come up without any form of ideology or worldview.
Explain the “third thing?” It would really help considering my whole comment is about how I cannot rationalise a third position.
If gender is man-made, I don’t see what positive purpose it serves.
