I mean, there is biological science between it all.Yes we know the difference between a tranny girl and a real girl. We know. We're not stupid. But we also know the difference between a tranny boy and a real boy. It's not science. It's emotions. Mental. And you don't know the science of what makes one boy become Tom Brady and other boys turn into Giselle.
I don’t know who Giselle is, but I’m guessing Tom Brady has very different genetics and much higher test levels.
It’s all biological.
