Fluid gender is worse than transgender.
A transgender is 80%+ of the time a mentally ill man who wants/thinks he’s a woman, fewer than a quarter have the surgery, so the majority of transgenders are mentally ill guys with male plumbing demanding access to women’s spaces to validate the delusion.
Fluid gender isn’t even consistent on the delusion. Today I’m a man, tomorrow I’m a woman, whatever I feel like, it is fluid. It is also a category that lets a guy use the women’s bathroom today and the men’s tomorrow, and because it is a category, they can say that and defy categorization.
