This is my last post on this thread because it's very tiring and some of you are quite mean lol
I just thought I'd point out some more scientific reasons for the existence and validity of trans people:
Chromosomes/sexual development aside, studies have identified structural and chemical differences in the brains of transgender people, particularly in the regions that process sexual orientation and gender identity. The same part of the brain that influences sexuality (the reason why we're not all straight) can influence experiences of gender.
I know a lot of you don't believe in gender identity, but we do have neural networks related to it.
Trans people's brains have also display differences in networks associated with body perception and self-referential processing, which has been linked to gender dysphoria. Hormone related genes also contribute to dysphoria, and differences in gender identity.
Brain differentiation and genital differentiation can sometimes occur at different phases during a pregnancy. They are not always synchronised and can lead to mismatches. Exposure to testosterone in the second half of pregnancy can 'masculinise' the brain for example.
Feel free to fact check all this.
Obviously you're not going to change your minds, but I think it's important to state that transgender identities do have a biological basis of their own. Many of you simply argue that they don't exist, are deluded, or have an agenda.
I was ridiculed for saying this earlier, but nature truly is mysterious and surprising.
