A state employee has resigned and officials have disavowed an international advertising campaign that led to calls for an investigation of tourism posters proclaiming “South Carolina is so gay.”

The campaign, which plastered the London subway with posters advertising the charms of South Carolina and five major U.S. cities to gay European tourists, landed with a resounding thud in South Carolina, where the issue of gay rights has long been a political flashpoint.

The advertisements were timed for London’s Gay Pride Week, which ended Saturday. The posters touted the attractions of the state to gay tourists, including its “gay beaches” and its Civil War-era plantations.
