Under an agreement just signed between the European Union and the United States, airlines must provide personal information on passengers traveling to the U.S. from Europe, including details about their race, religion, political affiliations, sexual orientation and health.

“They're maintaining that this is about counterterrorism, but they're certainly not explaining why these specific categories are necessary to move toward that stated goal,” says Nancy Ordover, Assistant Director for Research and Federal Affairs at the New York-based Gay Men's Health Crisis (GMHC). “How is someone's sex life related to counterterrorism? Obviously there's something else going on here.”
