Starbuck is a woman. Get over it, and deal.
There's no reason Starbuck shouldn't be a woman. the archetype of a woman making it in a man's world as a reckless and carefree buccaneer sort is just as valid as the diamond-in-the-rough of Han Solo. The new Starbuck and Boomer also correct the imbalance of sexes found in the original Battlestar Galactica, which had Athena as a viper pilot only for a short period before dropping her completely.
The only disappointment I had in the casting was the decision to make Colonel Tigh white instead of black. That was partly because now none of the main crew was black, but also because Colonel Tye was the first black man to arrive in the Americas.
