Trans women are real women. Trans men are real men. Non-binary people are non-binary. All of us are real and valid. There have been studies on the physical make-up of transgender people, and most validate transgender people. Chromosomes and physical sex are not black and white. Intersex people are those whose primary and secondary sex characteristics don’t fit into the binary of male and female, often due to their chromosomes not aligning with the typical XX and XY pairings. Intersex people are as common as redheads. The animal kingdom also validates transgender people, as many animals enjoy homosexual relations and many can even change their sex.
