I'd agree that we can't easily divorce the two which is why I don't really get why we're expected to assume such a divorce here. To assume that despite the evidence that gender is influenced by genetics, hormones, and the structure of the brain that it can also turn on a dime when not a single piece of evidence actually shows this. All of the information compiled to substantiate genderfluid people could be compiled about transage people, about otherkin, about people with past lives. If they feel anxious, if they feel persecuted, if some culture somewhere has accepted them it really isn't evidence about the thing that actually matters: Is this genuinely thing you can be? Gender incongruence can be quite harmful because it's not a social club it's a disconnect at the biological level.
We know that transgender women are different from cisgender men, there is a body of evidence on it and despite the fog of the infinitely complex human psyche it's been proven. We've studied hormone uptake, information processing, and looked at brain scans and it's been pretty consistently shown that whatever's happening it looks quite a bit like what happens with cisgender people of the opposite sex. Please note all the things I didn't do when I just claimed and substantiated that transgender people were real. Never did I have to mention a culture that accepted transgender people, I didn't have to say what organizations were on board with the idea of their existence, I wasn't making wild extrapolations based on tangenitally related evidence, and I never had to say "talk to one there are a couple here." The facts suggesting transgender people are real speak for themselve just like supporting facts always should.
We just do not know that about gender fluid people. We just don't and accepting them as legitimate but not transage, transracial, or transable people is not being tolerant, open, or progressive, it's just the worst combination of dishonesty, myopia, and selective ignorance. You can't predicate your belief in someone's claims on their proximity to you or how sympathetic you find them because apart from it leading you to improper conclusions it's monstrously unfair to people who you don't know or don't like.
