How far does Sotomayor's empathy go?

Much has been made by the right about Judge Sonia Sotomayor's "empathy" standard when it comes to her judgments. It's not so much that that I'm questioning, but rather, how far does it extend? Will she extend her empathy to the still-unidentified group of people that her possible future colleague Justice Ruth Bader Ginsburg had stated that we "don't want to have too many of (quote is from last page)"? Who are those undesirables that Ginsburg refers to, anyway? Is it perhaps related to this?

If Sotomayor is willing to extend her empathy to this group of people, then I might actually be able to support her entry into the Supreme Court.
