Forgive me, I see I need to be exact here, just in case people have not read all of my posts.
I am a male. I have XY chromosomes. Everything about my body tells me that I am male. I'm sure that if I got a brain imaging scan done, we would find that the majority of the sexual dimorphic brain areas would more closely resemble that of a male. The idea of spirit and soul aside, I believe our brains are our central processing unit. Despite my male body, somewhere in my CPU, in an area defined to express gender identity, it is out of whack. We don't know where this area is yet, but if our brain controls all of our perceptions and sensation, then necessarily it is my brain causing me to think this.
It is far more reasonable for me to believe that my XY chromosomes, while in my zygotal state, set off a chain reaction to form me into a male. A wash of hormones didn't change me to XY (as some have claimed), XY is established before I ever developed two cells meaning the inherent code in those chromosomes would determine how I developed. That doesn't mean there cannot be errors, but I believe those errors occur during development of my XY (male) body, not BEFORE the egg and the sperm met and determined XY. If I somehow developed as an imperfect female as an XY zygote, it means I have some seriously messed up DNA, that my Y chromosome more resembled and X chromosome in structure - but this is so far out there, I feel it impossible for that to occur. I do however feel that minor variations can occur - minor errors, that can mess one up later on. Heavens knows that once the gonads form and start pumping sex-typed hormones, all sorts of errors can happen to the developing genitalia resulting in intersexed conditions. Therefore it is not unreasonable, or I should say it is VERY reasonable to believe, that when the gonads form and start pumping those hormones, if physical abnormalities can occur in the genitalia, then physical abnormalities can occur in the brain. Does this mean my brain is suddenly "changed" into a female brain? No! It means I still have a male brain with abnormalities - some of which might make me feel I am female. So when my developing fetus is born and gains awareness of itself, it feels something is not right, something it cannot explain, something others cannot easily see, and something for which there is no medical test yet created that can determine.
As for GID not being a problem, one doesn't need to look far on this board or one of the others like it to see IT IS A PROBLEM. It causes undo amount of distress during childhood and beyond. It has negative social and psychological implications regardless if one chooses to treat it or not. Feelings of body/mind incongruence, depression, low self esteem, negative self image, destructive tendencies, and possible suicide are all tenants of this condition. If someone were to give me a pill that caused all of those side effects permanently, I'd decline it. Why? Cause they would be a problem! Having a baby, a temporary situation, has rewards that outweigh the risks for most women, so they accept it. It is not a problem. Do the rewards of having GID outweight the negative aspects? And if you are fortunate enough not to have negative consequences of your GID so much so that it isn't a problem, please teach the rest of us. 😉
