Gender identity is more like an improper set of body-drivers in the brain. To use a comparison from computers, if you put AMD hardware in your computer, but install an nVidia driver, the video card likely will not work as intended since your computer is missing some of the information needed to use all its features.

Similarly, the brains of trans people tend to have the wrong "drivers" for their body, which causes dysphoria.

Since we don't have fine-grained control over brains, we cannot "reinstall" the right driver, and it's a lot easier to fix the hardware. E.g. just as putting in the proper nVidia card to match the driver will fix the problem in a computer; adding estrogen/testosterone and maybe some surgeries allows the brain-drivers to communicate with the body correctly.

Differences in "transition completeness" make perfect sense in this way. If most of your drivers map to "female" equipment, but the "penis driver" is working properly, you have dysphoria about everything but that.

(Evidence from brain studies agree that there are variations in brain structure in trans people.)

That analogy just comes across as trans propaganda. The brain is not separate from the body, it is part of the body. There's not any hardware/software divide like we have in computing, that could have this 'body drivers' concept make any biological sense.

You commented on another comment about transsexuality I wrote, and as with the other, I also disagree with this one.

Saying that trans-people who don't undergo surgery are just people with a sexual fetish is very disrespectful, I think.

Crossdressing and Transsexuality are not the same thing, as you sure know.

There's also nothing wrong with people who crossdress, by the way.
