CMV: I don’t get the point of gender identity being separate from biological sex.

There are three possible modes for biological sex: male, female, and intersex. These are all defined by physical characteristics that can’t be changed without surgery and/or hormone injections. In the case where someone wants to seriously transition, they undergo a sex change surgery and take hormone injections. They do everything possible to transition *biologically.* 

One of my problems is that changing one’s gender identity is purely a mental construct, whereas one’s physical characteristics (including the distribution of neurotransmitters and hormones, which significantly effect behavior) are measurable and visible. Essentially, if someone only transitions socially, they are relying on themselves and everyone around them to buy into an ill-defined mental construct that only serves to benefit ONE person, the socially-transitioning. 

The second problem is that the very notion of “gender identity” attempts to codify someone’s identity. A person’s identity is malleable and completely incomprehensible to a different person. Yes people might have identity traits in common, but no two people express those traits the same way. To me it feels completely futile to apply definitive labels to someone’s identity, when the very concept of an identity is basically impossible to define in the first place.

Edit: So today I learned that the term “gender” makes even less sense than I originally thought. I’ve had to think reading the comments, and I’ve definitely learned a lot. I didn’t change my mind, but my opinion is certainly better informed now. If biological sex and gender identity are not the same, then *internal* suffering happens when a person has the two unaligned. Gender Dysphoria is a *mental illness* that is in the DSM-5. No one should be shamed or discriminated against for having Gender Dysphoria, but it’s definitely *not normal* and *should not be normalized.* This leads me to believe that even if the two are technically separate, they are *supposed* to be the same and can in most be cases treated as such.

I think your view is based on a category error. "Gender being separate from biological sex" is just a fact about the world: it's not the type of thing that has a point. What you are saying here is akin to saying "I don't get the point of Madagascar being separate from Africa." You're basically looking for a teleological explanation of something that isn't teleological.
