Archbishop Salvatore Cordileone has criticised a measure that will be on the San Francisco ballot come national elections in November that could result in new abortion-related signage having to go outside pregnancy centres.

The ballot measure called “ Proposition O” would require the signs to be placed outside of pregnancy resource centres that do not offer abortions, or do not refer for abortions.

“Why would anyone want to stigmatise a primary health care facility and a pregnancy resource centre that gives pregnant women support for having their babies?” the archbishop has said, urging Catholics to reject the proposition.
