Just because you identify with females, it still doesn't make you one. So I disagree with those who are saying "she" was just born into the wrong body. If you have XYs everywhere, you cannot be a SHE. Black and white. This part is not a grey area. You can be one, or the other. If you have both XX and XY in your DNA then we can talk. Or if you have XXY. But a XY is male, and a XX is female.

That being said, if you want to live your life that way, who am I to judge? Go for it. There are lots of people who identify mentally as the other sex, or somewhere in the grey area, and that is what the issue here is. That should not be disallowed, and frankly, even though I don't do it myself doesn't mean others can't. I try not to judge those sort of people.

If I met a "girl" somewhere who used to be a man, I'd be turned off. I don't know why, it's just ingrained into me. Is it wrong? This "girl" is good looking, and hooking up with "her" would be both strange and good (no worries for birth control LOL), but I don't know if I could actually do it.

On topic- if the rules clearly state (and it's a private contest) that a she must be born as a she, then the disqualification is just. Doesn't mean "she" shouldn't petition for them to change the rules, it just means this is an issue that society needs to reconsider.

Edit: a wiki link, from mykalberta's link above.

It's not so simple as just XX and XY, but I think my point is valid still.

You'll see that even in the wikipedia XY article that you linked to, it states that the classical XX vs XY understanding has changed significantly. (edit: jeez, my reading comprehension sucks. I see you acknowledge that it's more complicated than simple XY.)
The significant quote is this one:

We [are] entering this new era in molecular biology of sex determination where it's a more subtle dosage of genes, some pro-males, some pro-females, some anti-males, some anti-females that all interplay with each other rather than a simple linear pathway of genes going one after the other, which makes it very fascinating but very complicated to study.

It appears to be a lot more complicated than simple XX vs XY, and if this understanding is correct, then there most definitely is grey area. That said, I agree with the rest of your post; it's entirely within your right and the rest of our rights to be uncomfortable with such a woman, and as for the contest, it's within their right, but up to the rest of society to question how we want to treat such cases.
