Do you honestly think that a biological male would try to transition into a female if they didn’t absolutely feel that it would rectify their gender dysphoria? A male who was happy in his body would feel too embarrassed or ashamed to do something that other men would view as ridiculous like transitioning into a female.
I have never seen anybody on here speaking badly of genuine transsexuals. I know somebody with gender dysphoria, and she has been living as a woman (woman’s name, women’s clothes etc) for three years now. She is a vulnerable person - despite hormones she still has the markers of a biological male and this can make her a target for some people.
HOWEVER. The problem we have is with self-ID. With this, any man could choose to identify as female (or a woman could identify as male) with no changes to lifestyle, no involvement from medical or psychological professionals. A man could choose to identify as female (without doing anything at all that would set him apart from other men) and could enter spaces designated for women, such as communal swimming pool changing areas, and nobody could challenge this.
An unlikely situation, but another one that explains why this is a problem for biological females: if I go to the doctors for a problem with my reproductive system, I can currently ask for a female doctor, because I’m not comfortable with a man examining me. I could arrive and have a person who presents as male, who quite clearly is a person with a penis, but who identifies as female provided. Would it make me a bigot for asking for somebody else?
