My GT is BrendanE 84 if you want to add me . I play most nights and on weekends Australian time . <| sep |> As a Mexican who grew up in the US , my input is irrelevant . <| sep |> The problem with your line of thinking is in the phrase Biological gender . Biological gender , in my fairly wellsupported by science opinion , does exist but it also doesn ' t refer to biological SEX . There are documented differences in the brains , both grey and white matter , and the concentrations of those things in specific areas of the brain , in trans people . Put simply , the brains of male to female trans people are more similar to women in those areas , and the brains of female to male trans people are more similar to men . And particularly notable is that some of the areas of the brain involved are the parietal lobe , which deals with sensory processing , and the frontal lobe , which is involved in planning movement . So , both parts of the brain that are involved in perception of your own body . t r a n s s e x u a l d i f f e rencescaughtonbrainscanSo , considering that the brain is the source of self , in every meaningful way , it ' s the source of all of your thoughts , personality , senses , emotions , and perception , why wouldn ' t it be more accurate to say that a MTF person is actually a woman who had to spend her whole life pretending to be a man , because relatively superficial at least , compared to the brain biological structures made her appear to be so ? Also you don ' t see random strangers ' DNA . Hell , unless you ' ve sent a cheek swab off to a lab to be tested , you most likely don ' t know your own chromosomes . People with androgen insensitivity syndrome can physically appear completely female , genitalia and all , despite having XY chromosomes . There ' s even been cases of people with XY chromosomes giving birth . There ' s also XX male syndrome , which like the name would lead you to assume , results in someone who looks typically male despite having XX chromosomes . Point is if you ' re a guy , and you did spontaneously decide to send off a sample to be karyotyped , and found you had XX chromosomes , would you then go Welp , I guess that must mean I ' m a woman , and change your entire life around based on that ? And if not , why not ? Maybe because it would . feel strange or wrong ? You ' re also not examining random strangers ' genitalia , and if you are you should probably knock that off . Trans people don ' t want to fool anyone . We just , like anyone else , want to be ourselves . Take a look at the scientific evidence , it does exist .
