But it's not only the complexity of the human experience that's the barrier to understanding but personal bias & this doesn't apply just to trans people but many issues where the defensive all purpose reaction 'word salad' brings much relief.
Gender being a particularly prickly issue for people with a bee in their bonnet about feminine & masculine expressions/inclinations….& maybe their lack there of. They like to convince themselves its purely a culturally enforced patriarchal phenomena when the reality is its another nature/nurture one.
The clue in an over reaction is how much of an hyperbolic existential threat an issue such as gender is made out to be. That such a trivial fact can induce such outrage & fear tells one there's much more going on 'beneath' than the social consequences of the issue itself.
The most conclusive evidence will never be enough for those in the grip of a complex but their 'early warning' reactions do serve a public service to 'handle with care'.
