The first one you may recognize as the 14th Amendment to the U.S. Constitution. The second one is part of an interview with Antonin Scalia, who as you may recall is a justice of the U.S. Supreme Court, a group that does things like decide what the 14th Amendment means.
This statement by Justice Scalia, which appears in the new issue of California Lawyer magazine, has caused some controversy, especially among women and men who wish to continue their current relationships with women. If the 14th Amendment doesn't extend equal protection to women, then a state legislature could repeal laws against discrimination, or pass laws that discriminated, and women would be stuck with that. Because that's what democracy is all about, you see.
