There Are Only 2 Genders

You said, "In science class/biology we are typically taught that all humans have ten fingers, But there are people in the world with abnormalities who have eleven or twelve fingers. Should we automatically dismiss them and pretend that they don't exist? " I'm not advocating to pretend people suffering from gender dysphoria don't exist. If you thought that was my argument, You are mistaken and I apologize for the miscommunication. I totally agree that intersex is a thing, I even acknowledged that. All I was saying was, I don't have any contentions with the concept of intersex. Abnormalities happen as a consequence of biology and those individuals need special consideration since their biologies vary in different degrees. This is directly analogous to the example you provided where individuals are born with 11 fingers. Intersex is very rare, But it does happen. When it does, Those cases need special consideration. Re sex/gender definitions/explanations: I am familiar with the terms sex and gender. I am not confusing them, I'm simply merging them. I do not agree that gender is it's own thing that lives on this intangible spectrum of endless fluid possibilities that can be flipped flopped freely based on ones mood. I think the entire concept is ridiculous and nonsensical. (more below) You said, "There have been different genders outside of man and woman for centuries. In India they have 3rd genders. Native American cultures have 3rd genders. In Ancient Egypt they have 3rd genders. It's a very western idea to say that there are only 2 genders and that this whole thing (that there are more than 2 genders) is a new idea changing our culture and society. " We, The Western world technically have 3 sex/gender categories as well (Male, Female and Intersex). I have no problem with this. My problem is with the idea of a gender spectrum that has infinite possibilities that can be freely changed at will. This spectrum feels like it's only purpose is to provide individuality for people who find it uneasy to be normal. Where do we draw the line? What if a person who is 11 feels like they are 21 - can they legally drink? What happens if a 30 year old man thinks he's a 15 year old girl and has sex with a 15 year old boy? This opens a huge rabbit hole for crazies. A woman who "feels" like a man, Cannot get testicular cancer. A man who "feels" like a woman cannot birth a child, Get ovarian cancer or have a period. There are clear physiological distinctions between sexes and having a dysphoria crisis does not change the underlying physiology. Our sex is tied to our physiology. Changing this will require a large list of social adaptations. For example, Laws will need to be rewritten. Should referring to someone by their biological sex be considered a hate crime? Another example could be medical treatment. If a 25 year old man walks into a doctor because he feels like he's got cervix pain - are doctors expected to actually take that seriously and perform female based tests on his male physiology? Gender dysphoria is a mental condition. The people suffering from this delusional thinking need help. I'm not saying ignore them or pretend they are not there. I'm just saying we should not give them platforms in society to advocate their nonsense and expect everyone else to change. They are disconnected from reality. We don't hand a microphone to a schizophrenic person and pretend we also hear the voices. This to me is no different.
