Judge Sotomayor is a liberal judicial activist of the first order who thinks her own personal political agenda is more important that the law as written. She thinks that judges should dictate policy, and that one's sex, race, and ethnicity ought to affect the decisions one renders from the bench...
She has an extremely high rate of her decisions being reversed, indicating that she is far more of a liberal activist than even the current liberal activist Supreme Court.
Sonia Sotomayer highly favors reverse racism, or as it's come to be known, Affirmative Action. One of her most high profile cases included Ricci v. Destefano, in which several New Haven firefighters were denied promotions due to "a lack of minorities" among those who passed the tests, including Frank Ricci who suffers from dyslexia and had spent 8 to 13 hours a day studying for the exam. You can review the details here, but Sotomayer sided with New Haven's decision to deny these firefighters a promotion.
Of course, anybody who rejects Sotomayer will be seen as racist or sexist, although we conservatives could give a crap about her skin color or her genetalia. It's always the left that's hung up on your pigment or what you have between your legs, as said by Sotomayer herself here:
In 2001, Sonia Sotomayor, an appeals court judge, gave a speech declaring that the ethnicity and sex of a judge “may and will make a difference in our judging.”
“I would hope that a wise Latina woman with the richness of her experiences would more often than not reach a better conclusion than a white male who hasn’t lived that life,” said Judge Sotomayor, who is now considered to be near the top of President Obama’s list of potential Supreme Court nominees...
This is identity politics. There is no racism or sexism here. We on the right are opposed to her views that "the courts make policy" meaning that she would be an activist judge and that since she's one that Obama "empathizes" with, she would dismiss the Constitution and rule based on just feelings and opinion. That is not how someone who is picked to sit on the highest court should rule. And if Obama wanted a Hispanic, Miguel Estrada could have been given a fair shake this time around.
