I always had to wonder about this, the bible says made male and female. Where does it say only male and female or that anatomy determines gender? It doesn't say that actions or self knowledge does either but then again, it doesn't say not.
Dinosaurs exist, I belong to a group which is christian and believes about dinosaurs with no problems and without changing what the bible says. Just because it doesn't mention cars in the bible doesn't mean they don't exist, same with dinosaurs or transgender people.
Grrr, Hope that Supreme court goes the right way.
