The difference has two components: genetic, personal. Genetic does not depend on self identification. Personal is very similar these days. Same families, same schools. As for trans. Humans, unlike most animals, cannot even have sex without being taught. The reason is humans for many generations, million years probably, lived in groups and learned how to do it. Those who didn't have genetically hardcoded knowledge how to make kids by the time they grew up they knew it any way. It wasn't necessary and with the time it was almost lost. The same with gender identification. Everywhere boys and girls where brought up differently. So, we lost hadcoded self identification. Today human kids may grow up thinking they are dogs, or wolfs, or sheep. If they happened to grow up with animals. Conclusion is it's parents responsibility to give kids the right identity. Failure to do it, some brainwashed wokes don't do it intentionally, results in miss self-identification. Add to that 'doctors' multi-billon industry preying on them and some schools playing along to keep parents uninformed. There was a couple of months back interesting article about navy seal who had mental problems. He was brainwashed into believing he was a woman, and needs treatment and surgeries, payed by government. Later he realized he was just used to make money, and became a man again. The same happens to kids en mass. Because they are easy targets.
